Frequently Asked Questions
Why do I see “unknown” under “Last Login” in the results table?
After the installation of this plugin, user login timestamps will be logged. But if an user hasn’t logged in yet since the installation of this plugin, the plugin has no way of knowing when the last login of this user happened. That’s when it displays “unknown”.
How does this plugin work?
WordPress passwords are stored in a irreversible way, so it’s not possible to obtain the original / plain-text password for anyone (that’s a good thing). The only way to validate an users password, is to compare a password to theirs and let WordPress determine if they are the same. So the only way to determine if a password is weak or not, is to compare it to a (very long) list of most used passwords and/or weak passwords. That is exactly what this plugin does. Note that at the time of writing this is the only plugin of it’s kind available on the market.
Is it possible to add custom passwords to the “weak passwords list”
Yes, this is definitely possible. Just navigate to the backend of your WordPress instance and open “Plugins > Editor”. Now click the “Select plugin to edit:” dropdown and select “WordPress Password Scanner”. Look for the file “weak_passwords.txt” in the right bar. Add your passwords at the bottom of the file (separated by new lines / ENTER) and click “Update File”.
Important: this file will be overwritten in an update of the plugin. Please send us an email containing the password of list of passwords you added. This so we can add this to the original list and your custom list will not be overwritten on update, but also so we can keep extending the list of weak passwords and thus improve security of all our customers.
How to change the “admin” username
The “admin” user is the default WordPress user and thus exists on every WordPress instance by default. This is a security vulnerability (hackers need to know two things to get in: an username and a password. Now they already know one of the two). Also the majority of attacks will target your wp-admin / wp-login pages, trying to log in with an username (very likely “admin”) and a password. It’s very easy to change this username to something more original and thus less likely to be guessed by hackers:
- Create a new user in your WordPress backend by navigating to “Users > New User”
- Give this user administrator rights:
- Log out of the WordPress backend and log in with your newly created administrator account
- Remove the old “admin” user:
- Important: to not loose any content of the previous “admin” user, assign this to the newly created one:
