Turning on 2FA provides an extra layer of security for your account, and is recommended for all users.

Click Settings
Click Set Up 2FA
Scan the QR code with Google Authenticator, Ente Auth, or any other OTP app.
Enter the verification code from your authenticator app, and 2FA will be turned on.
While you're here, download a set of backup codes which will give you access if you ever lose access to your phone or authenticator app. Ensure you safeguard these codes as they will allow someone to bypass the 2FA on your account.
If you have archived or deleted your account, you will have to set up 2FA on your device again. Make sure to delete the previous 2FA information before doing so.
