I am upgrading an older project to Laravel 5.7. User passwords were hashed with bcrypt previously. On the new setup hashing driver is set to bcrypt in the config file but still getting the following error.
local.ERROR: This password does not use the Argon2id algorithm. {"exception":"[object] (RuntimeException(code: 0): This password does not use the Argon2id algorithm. at vendor/laravel/framework/src/Illuminate/Hashing/Argon2IdHasher.php:20
Auth::attempt() returns true but login is not persisted on redirect.
I've read a few posts about people having issues with this. Perhaps this github issue will help you out, they're having similar problems: https://github.com/laravel/framework/issues/25586
Edit: This may help also, https://github.com/laravel/framework/issues/24162
