Currently 56% of all users have enrolled into passhash algorithm upgrade since June 2022.
Which includes:
1. User who registered since then.
2. User who have ever changed their password since then.

The Phase 1 enroll was done seamlessly without any side effects, but the enroll rate (The frequency our users changes their password) seems low.

The staff team decided to enter Phase 2, where users automaticically convert their passhash to new algorithm upon password login.
This will have a slight side effect, that from now on when the first time a user with old passhash login by password successfully, all other logged-in sessions of that user will expire. He/she will need to re-login on all other PC/browsers. It only happens once.

And, we do recommand all users change their password periodically (every 12/24/36 month or so) for improved account security.
