# 2-Factor Authentication
|
|
|
|
2-Factor Authentication is a security mechanism that requires you to enter a computer generated code from your phone every time you log into Mastodon.
|
|
|
|
We highly recommend that you set up 2-factor authentication as it prevents malicious users from logging into your account if they obtain your password.
|
|
|
|
## Warning
|
|
|
|
If you lose access to your 2-factor authentication (such as by losing your phone or performing a factory reset) and you do cannot log in, you will not be able to access your account and will need to contact an instance admin to remove 2-factor authentication from your account.
