# Setup two-factor authentication
Select *Administration* from the dropdown menu on the top right corner of the screen.
Go to the *Two-factor authentication* tab page and click on the `Add authenticator app` button.
Follow the instructions on screen and click on the `Verify` button.
A set of recovery codes will also be issued to you. Store these codes in a safe place, you will need them in case your authenticator app stops working or you do not have access to your device.
{% hint style="warning" %}
Each recovery code can only be used once.
{% endhint %}
You can renew your recovery codes by clicking on the `Reset recovery codes` button.
{% hint style="warning" %}
New recovery codes replace and invalidate all existing codes.
{% endhint %}
Using the `Reset authenticator app` button you can set up your authenticator app again if it stops working or you get a new device. Resetting also invalidates the codes from your old device, helping you protect your account if your mobile is lost or stolen.
