Looks like that error is from previous version. You are on latest v2.8. If you use a fake password for your username to login, will it still show that error?

An error always occurs when I log in with the password of the user name + the year as the admin user of WordPress.
There seems to be a problem when the plugin authentication part is called from WordPress itself.
On my site, I get an error when logging in with username admin and password admin2018.
Disabling this plugin will not cause any issues.
