@wplms24,
LifterLMS doesn’t automatically generate any passwords for students. If a student is creating an account they choose their password themselves and LifterLMS doesn’t choose that password for them.
We have a lot of requests to automatically generate passwords and send them by email but for security reasons this is a feature we’ve said publicly we will not build.
Are you using a plugin that does this? If so you’ll want to contact the plugin dev for assistance here.
If you’re actually creating users on the admin panel and using the WP Core auto generated password feature you can write up a little plugin using this filter: https://core.trac.ww.wp.xz.cn/browser/tags/4.9/src/wp-includes/pluggable.php#L2302
Or you could plug the whole function to create your own list of chars to generate the password.
Hope that helps,
