- [How do I see and sign out other devices?](https://support.bluedeer.ai/bluedeer/account-and-security/signed-in-devices.md): See every device signed in to your account in Settings, and sign out one device or all the other devices.
- [How do I change my name or password?](https://support.bluedeer.ai/bluedeer/account-and-security/change-name-or-password.md): Change your display name and your password in Settings under Account, knowing that a password change signs you out everywhere.
- [How do I turn on two-factor authentication?](https://support.bluedeer.ai/bluedeer/account-and-security/turn-on-two-factor-authentication.md): Turn on two-factor authentication in Settings with an authenticator app, so that signing in also asks for a 6-digit code.
- [How do I delete my account?](https://support.bluedeer.ai/bluedeer/account-and-security/delete-your-account.md): Delete your account from Settings after typing your email address to confirm, and it is deleted 30 days later unless you sign in again before then.
- [What are action confirmations and approval cards?](https://support.bluedeer.ai/bluedeer/account-and-security/action-confirmations-and-approvals.md): Some actions, such as sending an email, show an approval card in the chat first, and you choose how often Bluedeer asks in Settings.
