Select your initials at the top right of the app, then **Account security**. The page lists the ways you can sign in: Email link, Password, and Google.

## Passwords

- **Add a password** if you've only used email links or Google so far.
- **Change password** asks for your current one first.
- **Remove password** turns off password sign-in. You can still sign in with an email link, or with Google if it's linked.

New passwords need 10 to 128 characters. Spaces are fine, and common passwords are refused.

## Google

If Google isn't listed, use the Google button on the page to link your Google account. **Remove Google** unlinks it again. Google only confirms who you are. It never gives quickS3 access to anything in your Google account.

## Things to know

Every change here signs you out of your other browsers. It doesn't touch [AI clients you've connected](/docs/agents/manage-access/) or [share links](/docs/files/share-links/).

If the page says "For sensitive changes, disconnect and sign in again first", your session is too old for this kind of change. Select **Disconnect** from the same menu, sign in again, and come back.

Your email address is the key to everything else, because email links always let you in. Keep control of that mailbox, and if you use a password, keep it in a password manager.
