An authentication chain is a combination of authentication methods. A user must pass all methods in the chain to be successfully authenticated. For example, if you create a chain with LDAP Password and SMS, a user must first specify the LDAP Password. If the password is correct, the system sends an SMS with a One-Time-Password (OTP) to the user’s mobile. The user must specify the correct OTP to be authenticated.
You can create chains with multiple methods that are applicable for highly secure environments. You can create authentication chains for specific group of users in the repositories.
