# 2FA Two-factor Authentication (2FA) is a safety feature which provides an extra layer of security to your account. With 2FA enabled, logging in/changing your password/placing a withdrawal/etc., a **passcode**, which you will receive through your 2FA mobile app, will be required in order to confirm the action. This is one of the best ways to secure your account and the setup process is very easy so we strongly recommend you to enable 2FA for your account immediately after completing registration. Our 2FA system uses a TOTP solution which means it requires a Google Authenticator app. It’s more secure and reliable than using SMS as 2FA solution. ![](/files/-MOFD1pk-DFjhAOE7Kb3) To enable 2FA: * Download the Google Authenticator app for either iOS or Android * Go to [Settings](https://primexbt.com/my/home/settings) page of your account * Click ‘Enable 2FA’ button in Google Authenticator section * **Save your secret key in a secure, safe location** and confirm it by clicking on the box next to ‘I have backed up the 16-digit code’ * Confirm the setup by entering the PIN code generated by your 2FA app A Google Authenticator code will now be required in order to access your account or withdraw funds.\ \\ --- # 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.
