Multi-Factor Authentication (MFA), also known as Two Factor Authentication (2FA), enhances your account security by requiring more than just a password to log in.
When you enable MFA, Joplin Cloud will show you a list of codes that you should save somewhere safe. Each code can only be used once but you can generate new codes from your profile page.
If you cannot generate your authentication codes because you have lost access to your smartphone, for example, you will need to use one of the recovery codes to login.
The new codes will invalidate the old ones, so remember to save them.
