phpass PasswordHash timing out
[Thu Sep 24 10:12:49.066018 2020] [php7:error] [pid 15544:tid 2084] [client 10.0.16.1:45182] PHP Fatal error: Maximum execution time of 300 seconds exceeded in C:\\Apache24\\htdocs\\portal\\updates\\concrete5-8.5.2\\concrete\\vendor\\hautelook\\phpass\\src\\Hautelook\\Phpass\\PasswordHash.php on line 314
I can see that the error is coming from PasswordHash.php on line 314, but I'm struggling to figure out why.
NOTE: This site is a company portal that requires every user to login but I've been told that one department is sharing a username & password. I don't know if that's relevant.
