LGTM, thanks @avddvd!

@levb Is 5 minutes a practical time duration for this in your opinion? I suggested this duration in the HW ticket. I'm not sure if there is user intervention within that window. If it is all server-to-server talking, then we can go much lower with the duration.

LGTM. Thanks! 🎉

@mickmister The state of the OAuth has to live from the moment the user hits the link, until the login process is finished. Therefore, you have to take in account the time the user takes to put their credentials. I think 5 minutes is a reasonable time.

[levb]

I'd choose 15m myself, but 5 seems alright, too.

LGTM thanks @avddvd!

Tested and passed

• Regression tested authentication with multiple users
• Ensure authentication records are not accruing in the KV store
• Ensured time to live is respected
  LGTM!
  Thanks @avddvd for this improvement. Sorry for the delay on getting this tested.
