Sending a sensitive email usually means trusting the other person not to forward it, screenshot it, or leave it sitting in their inbox forever.
Gmail confidential mode gives a sender more control over that: it turns off the usual forward, copy, print, and download options on a message and its attachments, and it lets a sender set an expiration date or revoke access at any time.
This article covers how to turn it on in the Gmail app and on a computer, how expiration and passcodes work, and what the feature cannot do.

🔍 What Confidential Mode Actually Does
Confidential mode changes how a recipient can interact with an email once it lands in their inbox.
Normally, anyone who gets an email can forward it, copy the text, print it, or download attachments with no restriction.
With confidential mode turned on, those options are disabled for that specific message, which reduces the chance of a sensitive email getting passed along by accident.
It is important to understand what this feature is not. Confidential mode cannot stop someone from taking a screenshot or a photo of the screen, and Google notes that other methods or software may still allow copying or downloading in some cases.
Think of it as a way to lower the odds of accidental sharing, not a guarantee of total privacy. For truly sensitive information, like financial account numbers or legal documents, it is a good idea to treat confidential mode as one layer of protection rather than the only one.
💡 Key point: Confidential mode limits forwarding, copying, printing, and downloading, but it does not block screenshots or photos of the screen.
⚙️ Step-by-Step: Sending a Confidential Email
The basic flow is the same across devices, even though the exact menu names and icon positions can vary slightly depending on the app version.
Start a new email as usual, then look for the option to turn on confidential settings before sending.
- Open the Gmail app or Gmail on a computer and start a new message with Compose.
- Find the confidential mode option: on phones, tap More options (the three dots) and choose Confidential mode; on a computer, click the lock-and-clock icon at the bottom of the compose window.
- Turn on Confidential mode.
- Choose an expiration timeframe for the message.
- Under Require passcode, choose either Standard or SMS passcode.
- Tap or click Save, then finish writing the email and send it.
Once saved, the compose window usually shows a small indicator that confidential mode is active, so a sender can double check before hitting send.
💡 Field tip: Many people turn on confidential mode after they have already attached files and written the message, then wonder why the settings seem to reset. Setting confidential mode first, before adding large attachments, tends to avoid this kind of mix-up, since changing the toggle can sometimes clear draft settings depending on the app version.
📱 iPhone, Android and Computer Differences
The steps are nearly identical on iPhone, Android, and a computer, but a few small things differ depending on where a sender is working.
| Device | Where to find it | Notes |
|---|---|---|
| iPhone or iPad | Tap More options (⋮) in compose, then Confidential mode | Menu wording can shift slightly with app updates |
| Android | Tap More options (⋮) in compose, then Confidential mode | Same general layout as iPhone, icon placement may differ by phone model |
| Computer | Click the lock-and-clock icon at the bottom of the compose window | Labeled Toggle confidential mode when hovered over |
On mobile devices, the confidential mode settings appear as a separate screen that a sender fills out and then saves before returning to the main compose window.
On a computer, the same settings appear in a small pop-up box directly inside the compose window, which can make it easier to see the expiration and passcode options side by side.
Work or school Gmail accounts may have this feature restricted or turned off entirely by an administrator, which applies the same way across iPhone, Android, and computer versions of the app.
🛡️ Setting an Expiration Date and Passcode
Expiration and passcode settings apply to both the message text and any attachments included in that email.
The expiration timeframe determines how long the recipient can open and view the confidential email before it becomes inaccessible through that link.
The passcode setting determines how the recipient proves their identity before reading the message. With Standard, a Gmail-to-Gmail message opens directly for the recipient, while someone using a different email provider receives a passcode by email to unlock it.
With SMS passcode, the recipient receives a one-time code by text message instead, which adds a layer of verification tied to a phone number rather than an email inbox.
- ✅ Choose SMS passcode when sending to someone outside your usual contacts, since it ties access to a phone number.
- ✅ Choose a shorter expiration window for anything time-sensitive, like a one-time link or temporary access code.
- ✅ Confirm the recipient’s phone number is current before choosing SMS passcode, since an old number will block access entirely.
Because security settings like these can change with updates, it is a good idea to check Gmail’s official help page or contact support directly if the exact wording or behavior looks different from what is described here.
⚠️ Watch out: If a recipient’s phone number changes after an SMS passcode email is sent, they may be locked out of the message entirely with no easy way back in.
✅ Removing Access Early
A sender can cancel access to a confidential email before its expiration date arrives, which is useful if the message was sent to the wrong person or is simply no longer needed.
To do this, open the Sent folder, open the confidential email in question, and select Remove access.
On a phone, this option usually appears at the bottom of the open message rather than in a dropdown menu, so scrolling down may be necessary to find it.
Once access is removed, the recipient can no longer open the message through that confidential link, even if the original expiration date had not yet passed.
💡 Field tip: To confirm removal worked, reopen the sent message after tapping Remove access and check that the confidential banner now shows the message as expired or inaccessible, which usually happens within a few seconds without needing to refresh the app.
📋 Useful Ways to Use Confidential Mode
Confidential mode tends to be most useful for messages where the main goal is limiting casual forwarding rather than achieving airtight security.
Sending a temporary password, a link to a private document, or a short-term access code are common situations where a short expiration window fits naturally.
Setting a passcode requirement adds a small extra step for the recipient, which can be worth it when an email contains something a sender would rather not have sitting unprotected in someone else’s inbox indefinitely.
It also works well for internal reminders to be careful: even if confidential mode does not block screenshots, the presence of the restricted banner signals to the recipient that the content is meant to stay private, which can reduce casual re-sharing.
For anything genuinely high-stakes, like legal contracts or full financial account details, it is a good idea to pair confidential mode with other precautions, such as a phone call to confirm receipt or a separate secure file-sharing service built specifically for sensitive documents.
🔧 If the Option Does Not Show Up
If Confidential mode is missing from the compose menu, a few common causes are worth checking first.
- Confirm the device is using the actual Gmail app or Gmail through a browser, rather than a different email client that does not support this feature.
- Update the Gmail app to the latest version, since older versions may not display the option or may use different wording.
- If using a work or school account, ask the administrator whether confidential mode has been restricted or turned off for that organization.
- Try searching for Confidential directly in the app’s settings search bar if the menu location has changed.
💡 Field tip: A common misconception is that confidential mode is a Gmail-wide setting that stays on for every email. In reality, it has to be turned on individually for each message, so a missing option is more often a sign of checking the wrong menu than a sign the feature is disabled.
⚠️ Things to Watch Out For
The single biggest misunderstanding about confidential mode is treating it as a way to fully prevent information from being copied or shared.
Google is explicit that it does not stop screenshots, photos of the screen, or certain other copying methods, so sensitive information can still end up outside the intended recipient’s control.
Setting an expiration date or using Remove access only limits future access through that confidential link. It does not erase or recall anything the recipient already viewed, copied, or saved before access was cut off.
Because of this, confidential mode works best as a precaution against casual accidental sharing rather than a defense against someone determined to keep a copy of the content.
For highly sensitive material, it is worth pairing confidential mode with judgment about who actually needs to receive that information in the first place, since no email feature can fully substitute for that kind of care.
🙋 Frequently Asked Questions
Q. Can a recipient still screenshot a confidential email?
Yes. Confidential mode disables forwarding, copying, printing, and downloading, but it cannot block screenshots or photos taken of the screen.
Q. Does confidential mode work for attachments too?
Yes, the expiration and passcode settings apply to both the message text and any attachments included in that email.
Q. What happens to the email after it expires?
The recipient can no longer open the confidential message through that link once the expiration date passes, though this does not remove anything they already viewed or saved beforehand.
Q. Can confidential mode be used with any email provider?
It can be sent to any email address, but recipients outside Gmail receive a passcode by email under Standard mode rather than opening the message directly.
Q. Is confidential mode available on work or school Gmail accounts?
It depends on the organization. Administrators can restrict or disable confidential mode, so it is worth checking with an IT department if the option does not appear.
Q. Does removing access notify the recipient?
The message simply becomes inaccessible through the confidential link after Remove access is selected; checking the Sent folder is the way to confirm the change took effect.
Q. Is SMS passcode more secure than Standard?
SMS passcode adds a verification step tied to a phone number, which can add a layer of protection, but it depends on the recipient’s phone number being current and accessible.
