Can Canvas LMS See If You Switch Tabs?

Canvas cannot see which other tabs, windows or apps are open on a student's device. What a Canvas quiz does record, according to Instructure's instructor guide (checked Sep 2026), is the moment the quiz page stops being the active page: after 15 seconds in another tab or window, or after 30 seconds without a click inside Canvas, the log writes "Stopped viewing the Canvas quiz-taking page".

No alert goes to the instructor. The entry sits in a per-student log that Canvas deletes after six months, and the same guide tells instructors that the log should not be used to identify cheating.

What Does Canvas Actually Record During a Quiz?

Canvas is a website, and a website only knows what happens on its own pages. The quiz log for a Classic Quizzes attempt therefore holds a short list of event types, each stamped with a time: the attempt start, questions viewed, answers saved, the page losing focus, and the page regaining it.

Instructure's guide describes the log as a tool for investigating problems a student had in the quiz, and for insight into the questions themselves.

The detail that surprises most students is what the busiest entry omits. When the quiz page goes out of view, the log records only that fact. The University of Colorado Boulder's Canvas documentation states it plainly: the log will not show what the student went to, only that they left the quiz page.

Two more properties shape how instructors read it. Autosave fires whenever a student moves to another question, so Fill-in-Multiple-Blanks, Matching, Multiple Answers and Multiple Dropdown questions can appear "answered" at the very start of an attempt. Instructure states the log is not accurate for those 4 types.

And the log is temporary. Six months after the attempt, it is gone.

How Does the Quiz Log Detect Tab Switching?

The mechanism is ordinary browser behaviour, not surveillance software. Every web page can ask the browser whether it is currently visible and whether it has focus. The Canvas quiz page checks this, waits, and writes an entry if the page stays hidden past a threshold.

The thresholds come from a Canvas Community explanation that Georgetown's instructional continuity office repeats in its exam guidance: more than 30 seconds inactive inside Canvas, including moving to another Canvas page, or more than 15 seconds clicked out of the quiz to another tab or window. When the mouse moves or clicks on the quiz page again, the log records "Resumed".

A student who switches tabs for 10 seconds produces nothing. A student who stares at a hard question for 40 seconds without touching the mouse produces the same line as a tab switch.

That second case is why university teaching centres warn instructors off quick conclusions. CSU Chico's knowledge base lists many legitimate reasons the entry appears. An October 2025 Instructure Community thread asked administrators to interpret a run of "Stopped viewing" entries on an attempt taken on a Windows laptop with intermittent display-controller faults and no proctoring software involved.

Classic Quizzes and New Quizzes now log the same event, but they did not always.

New Quizzes gained the "stopped viewing" and "resumed" entries in its Moderation Log in October 2024, according to Newcastle University's learning technology team, which noted Instructure's own caveat that the log could produce false positives. Before that update, a New Quizzes attempt showed start, answers and finish only.

New Quizzes also has a setting Classic never had. When an instructor turns on Detect Multiple Sessions, Canvas collects information about attempts that ran across more than one session, browser or device. Instructure's permissions documentation restricts viewing that data to roles granted "New Quizzes - view multi session information"; whether course instructors hold it is an institutional decision.

Three limits apply to both engines. Quiz Log Auditing is a course opt-in feature in Instructure's guide, and a Canvas Community answer from February 2025 confirms it is not retroactive: a course that never enabled it has no log to open. Logs are retained for six months. And the 4 autosave-affected question types cannot be read as a sequence of events.

The log, in other words, can establish that a page lost focus for at least 15 seconds.

It cannot establish why, where, or whether anything was looked up.

Can Teachers See If You Switch Tabs?

Yes, if they go looking. The path in Classic Quizzes runs Quizzes, then the quiz name, then Options, then Show Student Quiz Results, then a student's name, then View Log. Each log covers one student and one attempt, and a quiz with several attempts defaults to the latest.

Nothing pushes the entry to the instructor. No email, no dashboard flag, no gradebook icon.

The r/UCDavis thread that ranks first for this question repeats a roommate's claim that the professor gets a notification every time a student clicks off the quiz page. Canvas has no such feature.

An instructor who wants to know must open View Log per student. In practice, most check only the attempts that already look unusual: a score far above the student's average, or a finish time far below the class median.

What they see is the time-stamped entry, the "Resumed" entry after it, and the gap between the two. Instructors who read logs as evidence tend to look at two things: how many gaps an attempt contains, and whether an answer changed right after one.

Canvas shows the student nothing either.

There is no on-screen warning when focus leaves a Classic or New Quiz, which is the opposite of Proctorio's black screen and countdown.

Instructure's guide is explicit about the next step. Instructors with an integrity concern are told to first work with the academic affairs office, academic technology office, or whichever unit handles misconduct, and to follow that office's approved process. The log is a starting point for a conversation, not the end of one.

What If the Quiz Is Not Proctored?

An unproctored Canvas quiz has exactly one record of the session: the quiz log described above.

No webcam, no screen capture, no list of sites, no keystrokes.

This is the narrowest answer in the article. The log can show that the page was hidden for more than 15 seconds. It cannot show what happened during that time, and it cannot distinguish a search from a phone call.

Whether leaving the page matters at all depends on the rules of the assessment, not on the log. "Open-book" is a list, not a licence. The UTS 26134 final, documented in AskSia's Explore library, permits paper notes, the textbook, any calculator and offline Excel, Word or PDF files, bans the internet and cloud-stored notes, and runs through ProctorU's Guardian browser rather than a bare Canvas page.

Read the quiz instructions as that kind of list. If an instructor writes that notes are allowed in another tab, a "Stopped viewing" entry is irrelevant. If the instructions say closed-book, the entry is the least of the problem.

Two habits remove most of the ambiguity. Close every other tab and silence notifications before you click Take the Quiz, so any entry that appears is one you can explain. And if you left for a real reason, a crash, a dropped connection, a call, message the instructor with the time before they open the log, not after.

The rest is preparation. A student who has worked through the material in advance has nothing to look up. The AskSia guide to studying for exams covers the six-week version, and the AskSia quiz generator turns a set of lecture slides into practice questions in the same multiple-choice format Canvas uses.

What Do Proctoring Tools Add to Canvas?

Everything the quiz log lacks.

A proctoring integration sits on top of the quiz; the integration, not Canvas, does the blocking and recording. Three products cover most university deployments.

Respondus LockDown Browser replaces the browser. University IT guides for it at Stevens, Boise State and Nebraska agree on the core behaviour: the quiz opens full screen and cannot be minimised or exited until submitted; printing, copying, screen capture and keyboard shortcuts are disabled; and other applications, including messaging, screen-sharing, virtual machines and remote desktops, are blocked. Respondus Monitor adds webcam and microphone recording for unproctored sittings.

Nebraska's ITS guide adds the honest caveat: a student could still use another computer or a smartphone, so the university recommends pairing LockDown Browser with a proctored lab.

Proctorio runs as a Chrome extension configured per quiz. Utah Valley University's settings guide describes three grades of Force Full Screen: Lenient ends the attempt after 30 seconds out of full screen, Moderate after 15, Severe immediately. Only One Screen forces extra monitors to be unplugged, Disable New Tabs and Close Open Tabs do what they say, and Record Web Traffic keeps URLs and screenshots of any site visited.

Honorlock records webcam, screen, audio and web activity, checks an ID photo and asks for a room scan, per its Canvas instructor guide and UW-Madison's student FAQ. Its Browser Guard blocks new tabs and windows. Its Secondary Device Detection is narrower than the name suggests: it flags phones and tablets that open seeded test-bank pages, and Honorlock states it does not monitor devices on the student's network.

The matrix is the reason a single answer to the search question is impossible. On a bare Canvas quiz, a tab switch is a log line. Under LockDown Browser it is not possible. Under Proctorio's Severe setting it ends the exam.

The same split applies on other platforms.

The Moodle version of this question turns on plugins rather than core settings, as covered in can Moodle track tabs.

Does Canvas Track Tabs Outside Quizzes?

No. Outside a quiz attempt, Canvas has no focus timer at all.

What it keeps is a per-student access report: each content item opened, how many times, whether they participated, and when they last looked.

A view is counted each time a user opens the content URL or downloads an attachment, according to Instructure's guide. Ten views of a reading can mean ten careful sessions or ten accidental clicks; the report does not measure time on the page.

Instructors reach it through People, then the student's name, then Access Report. It complements the Total Activity column on the People page and the weekly online activity charts in New Analytics. Details older than two years are no longer available.

None of it sees another tab, another site, or another device.

This is the layer where a study workflow belongs, well away from the quiz page. 

Its Chrome extension for Canvas adds a Sync to AskSia button to every course card. The sync is read-only, never writes to Canvas, and copies lectures, slides, readings and the syllabus into a personal library that sits beside the public Explore collection of course guides. Installing is free, with one course sync included.

Frequently Asked Questions

Can Canvas see if you have two tabs open?

No. Canvas keeps no inventory of open tabs, and Instructure's quiz log guide (checked Sep 2026) lists no event for tab count. Two tabs open in the background produce nothing in the log as long as the quiz tab stays in front. The only related entry is "Stopped viewing the Canvas quiz-taking page", which the Canvas Community explanation ties to more than 15 seconds spent in another tab or window, and even that line says nothing about how many tabs exist. New Quizzes' Detect Multiple Sessions setting is often mistaken for tab detection; it records attempts that span more than one session, browser or device, and Instructure gates who can view it behind a separate permission. The practical move is to remove the question entirely: close every other tab before starting, and rehearse under the same one-tab condition with AskSia's Mock Exam mode, which runs adaptive practice in the real exam format and grades each answer with a rationale.

Can Canvas see if you copy and paste?

Not as an event. Instructure's quiz log guide (checked Sep 2026) records four things during an attempt: a question viewed, an answer saved, the page losing focus, and the page regaining it. Copying text from a question or pasting into an answer box is neither, so the log shows only the answer that was saved and the time it was saved. What can appear is the side effect: pasting into another site means leaving the quiz page, and after 15 seconds that writes the same "Stopped viewing" entry as any other tab switch. Proctoring changes the answer. Boise State's LockDown Browser guide states that copying and pasting anything to or from an assessment is prevented, and Proctorio's Disable Clipboard setting blocks it outright while its behaviour settings can flag copy and paste attempts, per Texas State's quick reference. For assignments rather than quizzes, Turnitin compares submitted text against its database after the fact, which catches the copied words rather than the paste. If a written answer may draw on prepared notes, confirm with the instructor in writing whether pasting from them is permitted, and type the answer in the field otherwise.

Can Canvas detect switching tabs on phone?

The quiz page behaves the same way on a phone as on a laptop, because the trigger is the page reporting that it is no longer visible. Switch to Messages for more than 15 seconds mid-attempt in a mobile browser or the Canvas Student app, and the log can show the same "Stopped viewing" entry, per the thresholds described in the Canvas Community and repeated in Georgetown's exam guidance. The line does not say "phone". Device details exist only in New Quizzes, only when Detect Multiple Sessions is on, and only for roles holding the "view multi session information" permission in Instructure's documentation. The larger risk on a phone is accidental: a call, a banner or a screen lock can each hide the page past the threshold. Take graded quizzes on a computer with notifications off, and keep the phone for revision, where AskSia's Flashcards with FSRS scheduling can be tuned to the quiz date.

Can Canvas detect if you switch desktops?

Canvas cannot tell a virtual desktop from a tab. Moving to another Space on macOS or another desktop in Windows Task View hides the browser window, so the quiz page reports the same hidden state it would for a tab switch, and after 15 seconds the same entry appears. Nothing in the log identifies the cause, which is exactly why Instructure says the log should not be used to identify cheating. Under proctoring the picture changes. Proctorio's Force Full Screen treats leaving the exam window as leaving the exam, ending the attempt after 30 seconds, 15 seconds or immediately depending on the instructor's setting, per Utah Valley University's guide. Respondus LockDown Browser disables task switching altogether. If a quiz permits a calculator or a notes file, ask whether it may sit beside the quiz on the same screen rather than on another desktop, and keep formulas on paper so the page never has to leave view.

Can Canvas detect screenshots?

Canvas has no screenshot event. Instructure's guide lists viewed, answered, stopped viewing and resumed, and nothing else, and a keyboard capture does not by itself move focus away from the quiz page. Detection arrives with the add-ons: Respondus LockDown Browser disables screen grab, printing and copying according to the student guides at Stevens and Boise State, Proctorio's Disable Printing option blocks screenshots as well as printing per the Los Rios faculty guide, and Honorlock records the screen for the length of the exam. Detection and permission are separate questions. Most university integrity policies treat reproducing secure assessment content as misconduct whether or not a tool caught it, so a screenshot of a closed-book quiz is a policy problem before it is a technical one. Ask the unit coordinator whether past quiz questions are released for revision; many courses publish them in Canvas after the availability window closes, which makes a screenshot pointless as well as risky.

Does Canvas detect cheating?

Canvas has no cheating detector. Instructure's own guide states that quiz logs are not intended to validate academic integrity or identify cheating, and directs instructors with concerns to their academic affairs office. What Canvas provides natively is evidence of activity: the quiz log, the course access report, and New Quizzes' Detect Multiple Sessions data. Everything that looks like detection comes from tools institutions license separately and connect through LTI: LockDown Browser, Proctorio, Honorlock, and Turnitin's similarity and AI-writing reports for assignments. Whether any of them is active is set per course and per quiz, so one university can run a unit with nothing and the next unit with webcam proctoring. The honest test for students is the assessment's rules, not the toolset; Read if you are wondering whether using AI counts as cheating, it walks through how universities draw that line. 

Final Thoughts

Every statement above describes Instructure's documented behaviour as of September 2026 and the vendor settings as published in university guides. Three things can change it.

Institutional configuration comes first. Quiz Log Auditing may be off for a course, the multi-session permission may have been granted to instructors, and a university can run its Canvas instance with local defaults, as described for Adelaide University's Canvas.

Product updates come second. New Quizzes gained the focus-loss entry in October 2024 without any change to the Classic log, and Instructure's release notes are the only reliable record of what the next update adds.

Assessment rules come last and matter most. This article describes what gets logged.

It does not describe what is permitted, and the two are decided in different places: one by Instructure's engineers, the other by the unit's assessment policy. When the two disagree, the policy wins.
