What is the RADIUS authentication?

RADIUS (Remote Authentication Dial-In User Service) is a client-server protocol used primarily for authentication and authorization of users during dial-up connections in corporate networks. Password Safe can also benefit from the advantages of a RADIUS server. In particular, multi-factor authentication should be mentioned here. But all other RADIUS-typical functions can also be used. Further information can be found for example at Wikipedia.


In order for Password Safe to address a RADIUS server, the following requirements must be met:

  • A RADIUS server must be available and accessible via the network.
  • Access to the Password Safe AdminClient must be set up on the RADIUS server.
  • A corresponding Secret must be configured for access.
  • In Password Safe, users must have been imported from the AD in masterkey mode.


The actual connection of the RADIUS server is simple:

Use RADIUS First; the usage is activated.
Host Address The address of the RADIUS server is stored here.
Secret Refers to the secret stored for the Password Safe AdminClient.
AUTH Port The so-called AUTH port of the RADIUS server is specified here.
ACT Port The ACCT port of the RADIUS server can also be stored; if required.
Timeout The time the RADIUS server has to react; can also be configured.
