Owin authentication password

20 Mar 2018 by Richard Deeming

You can't, and you don't need to. There are very few situations where you would ever need to know the plain-text password - primarily if you're using it to authenticate to a third-party system. For 99% of applications, you never need to know the plain-text version of the stored password.

Owin authentication password

20 Mar 2018 by OriginalGriff

You don't, that's the whole idea. Hashes are deliberately non-reversible, that's the whole point - nobody stores the password in a format that can be stolen. You use the hashed value - you can store that and use it for your autologin.
