After logging in, you will have the choice to receive a verification code via your e-mail address or an authenticator app. For this, you can use any standard authenticator app, such as those of Goofle and Microsoft. Consult the guide about configuring authenticator apps.
For applications where you can now login with just your username andpassword, you will have to supply your verification code only once a month, as long as you use the same browser on the same device.
Before you can set up the authenticator app, a one-time password will be sent to the e-mail address associated with your account. Then you will be presented with a QR code that allows you to link your account to the chosen app.
We recommend using a personal e-mail address whenever possible. If your account it is linked with an e-mail address that multiple people have access to, we recommend that you coordinate with your colleagues when setting up the MFA. The e-mails sent with the one-time passwords do not mention which user is concerned.
