Sending something sensitive, like a contract figure or an account detail? Gmail's confidential mode lets you set an expiry date on an email, take back access whenever you want, and switch off the recipient's options to forward, copy, print, or download it. This guide walks through it step by step with real screenshots from Gmail on the web.
Quick answer
Click Compose, then click Toggle confidential mode (the padlock with a clock) at the bottom of the message window. Choose an expiration, choose No SMS passcode or SMS passcode, click Save, and send. To cut off access early, open the email in Sent and click Remove access.
Confidential mode at a glance

|---|---|
| Where to find it | Bottom toolbar of the compose window: Toggle confidential mode (padlock with a clock) |
| Expiration choices | Expires in 1 day, 1 week, 1 month, 3 months, or 5 years (Gmail shows the exact date beside your choice) |
| Passcode choices | No SMS passcode (Gmail users open it directly; people on other email services get a passcode by email) or SMS passcode (sent by text to a phone number you enter for the recipient) |
| What recipients can't do | Forward, copy, paste, print, or download the message text and attachments |
| What it can't stop | Screenshots, photos of the screen, or malicious programs copying the message |

Step 1: Turn on confidential mode in a new email
- Open Gmail on your computer and click Compose.
- Add your recipient, subject, and message as usual.
- At the bottom of the compose window, click Toggle confidential mode, the padlock with a small clock. If you already turned it on, click Edit in the banner at the bottom of the email instead.

Step 2: Choose an expiration and a passcode
The Confidential mode window opens. It reminds you that recipients won't have the option to forward, copy, print, or download the email.
- Under Set expiration, click the drop-down and pick how long the email can be opened: 1 day, 1 week, 1 month, 3 months, or 5 years. The date it expires appears next to the menu.

- Under Require passcode, choose No SMS passcode or SMS passcode. Google generates every passcode for you. If you pick SMS passcode, enter the recipient's phone number, not your own.
- Click Save.

Step 3: Check the banner and send
Back in the compose window, a banner at the bottom shows when the content expires and repeats that recipients can't forward, copy, print, or download it. Click Edit to change the settings, or the X to turn confidential mode off for this email. When it looks right, click Send.

Step 4: Remove access early (optional)
Changed your mind, or sent it to the wrong person? You can cut off access before the expiry date.
- On the left, click Sent.
- Open the confidential email. Your copy shows the expiry date in a banner.
- Click Remove access. The recipient can no longer open the message or its attachments.

What the recipient sees
- Gmail users open the message in their inbox. If you required an SMS passcode, they click Send passcode, get a text, enter the code, and click Submit.
- Other email services (Outlook, Yahoo, Thexyz and so on) get an email with a View the email link. They request a passcode, which arrives by text or email, then enter it to read the message.
- Until it expires, the forward, copy, paste, download, and print options are switched off, and the message shows a note saying so.
Tips
- It is not encryption. Confidential mode limits what recipients can do in Gmail, but they can still take a screenshot or photo. For truly sensitive data, use a secure file-sharing link or an encrypted service as well.
- Pick the shortest expiry that works. One day or one week is plenty for most one-time details.
- Use SMS passcode for outside recipients when you want proof that the person holding the phone is the one reading it.
Frequently asked questions
Where is confidential mode in Gmail?
In the compose window, at the bottom toolbar, next to the insert photo and signature buttons. It is the padlock with a clock, labelled Toggle confidential mode when you point to it.
Can the recipient forward a confidential email?
No. Forward, copy, paste, print, and download are disabled for the message text and attachments. They can still take a screenshot, so don't rely on it alone for very sensitive information.
What happens when a confidential email expires?
The recipient can no longer open the message text or attachments. If they need more time, you can send it again with a new expiry.
Can I send a confidential email to someone who doesn't use Gmail?
Yes. They get a link to view the email and a passcode by email (or by text if you chose SMS passcode).
Why can't I see the confidential mode button?
If you use a work or school account, your administrator may have turned confidential mode off for your organization. Personal Gmail accounts have it by default.
