Authentication methods vs post authentication methods

Hi,

I need to write a paper and essentially it covers authentication methods?

I need to know authentication methods and how suitable they are for post authentication?

To my understanding and research all authentication methods are suitable for post authentication. Is it true?

Is there an exhaustive list for authentication methods that i can refer?

Best regards.

Could you provide more context?
I.e. Post auth waning handling. A token that will be continually presented when need to confirm identity.
Etc.

Hi;

It is rather generic.

e.g. a successful password authentication takes place but the system wants to do an extra authentication after this authentication (which makes it post-authentication).

I primarily need to know an exhaustive list of authentication methods.

Best regards.

You are talking two factor authentication.
post-authentication suggests that there is an active reaffirmation of who is authenticated.

Search for Two factor authentication and you will get various results
