# How do I enable two-factor authentication (2FA)? FinnGen uses Google's two-factor authentication (2FA) system, detailed [here](https://www.google.com/landing/2step/). FinnGen account can have separate Chrome profile equaling any other gmail account. Please note that many Google services are not enabled with FinnGen account (drive, gmail, youtube etc). FinnGen account's 2FA can be changed and configured in the Google account settings [here](https://myaccount.google.com/security). Note that you can also reset the phone number used for 2FA in the Google account settings. However, to do this, you must still have access to your old phone number. We recommend using the Google Authenticator app as the second step for added security. If you have forgotten to set 2FA in two week grace period or have lost your 2FA device (mobile phone etc.) please contact . --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
