This fixed my problem:

If you need to reset your admin password because you lost access to your admin account do so following these steps:

Once you have admin access, at dashboard go to the left side menu Security->Settings and scroll down to “Strong Passwords” and uncheck “Enable Strong Password Enforcement.” Save all changes and you should be good to go.

Also, the old password being replaced was 30 characters long which may be relevant.

I’m actually seeing this same error.

1. Enable strong passwords in iThemes Security.

2. Logout and go to the site’s frontend “Forgot password” page. Fill in username or e-mail address to get the admin password reset e-mail, follow the link to it.

3. Try to set the new password anything and click “reset password”. The error then shows as:

Fatal error: Call to undefined method stdClass::get() in /home/***sitename***/public_html/wp-content/plugins/better-wp-security/modules/free/strong-passwords/class-itsec-strong-passwords.php on line 68
