Analyzing application tags

Blitz Identity Provider allows you to assign tags to applications and set the operation logic regarding the tagged apps in login procedures.

To retrieve application tags, a procedure must use the ctx.appTags() method within Context.

Attention

For the method to work, you must import java.util.Set.

An example of a procedure that obtains the 2F tag and uses it to enable the second factor authentication:
