# Loss of a second factor

The following procedure may be used when a user needs to access a protected application, but doesn't have his second authentication factor available:

* The user may enter its login/password on `https://mydomain.trustelem.com`.

* Instead of activating the usual second factor, he/she selects **« Use an alternative method »**.

* The user may then ask a rescue code:
  * He has to click on **« Ask for a rescue code »**.
  * All administrators receive an email alerting that a rescue code is requested by a user.
  * One of the admins has to click on **« Rescue code »** in the **« Alerts »** tab of the Trustelem admin dashboard.
  * This code can be transmitted to the user, after having properly checked the user's identity.
  * The user has **24h** to use this one-time rescue code.
