Lag on callback processing

[theferrit32]

After authenticating with a backend, there is a multi-second lag while handling the callback and performing other operations. This could be dependent on the user and on how many frequently they log in fresh, which impacts how much state is attached to their user account in the db.

Could be a loop that is having to retrieve rows into python memory to decrypt.

Mitigation options: switch to hash comparison for state value, or stop encrypting it. The values are strictly time limited to a short window of usability and even then do not provide a lot of value on their own without also being combined with the nonce, which is still encrypted.
