This plugin provides uncomplicated 2FA plugin for WordPress. It will allow you 
to require a second, one time password or OTP, code to be entered when certain 
(or all) users attempt to log in to WordPress.
It will send a six-digit code via e-mail to the user attempting to log in. The 
code has a limited lifetime (defaults to 15 minutes). Once a code has been 
consumed, it is considered invalid.
You may configure that only certain roles are required to use 2FA, and it is 
recommended that you enable 2FA for those users with privileged access.
You may also configure the plugin to allow certain roles to enable an OTP code 
bypass, which will set a cookie in that user’s web browser. The cookies are 
partially based on the username, so several users can share the same browser, 
but still be required to always enter the OTP code, or bypass it if the cookie 
is present.
You can add custom text to the OTP code entry form, and you can add custom text 
to the OTP code e-mail message.
The plugin can be configured to allow it to be handled/managed only by specific 
users, thus making it harder for someone to accidentally or intentionally 
deactivate it. The implemented solution for this is by no means waterproof. If 
someone, for example, has access to your WordPress installation by means of FTP 
or similar, the plugin files can be physically removed (or moved out of your 
WordPress installation), which basically deactivates the plugin as well.

Cloudbridge 2FA

Uncomplicated 2FA plugin for WordPress. Tested with WordPress 5.5+ and PHP 7.4+.

WordPress uses phpass to store passwords. Because WordPress has to work everywere, it uses the portable version of phpass, 
which uses MD5 to hash passwords. MD5 is not a very good hashing algorithm for passwords, because it’s relatively fast.
This plugin switches over to bcrypt, which is the algorithm recommended by phpass, and is a much better option for password 
storage because it is much slower to produce. This makes it much harder for an attacker who’s managed to access your hashed 
passwords to obtain plain text passwords by brute-forcing, or by trying passwords from a dictionary.
Note: this plugin requires PHP 5.3.0 or newer
Be aware that if you use this plugin and then move to a host that does not support bcrypt, you will need to reset any user 
account that you want to log in with.

wp bcrypt switches WordPress's password hashes from MD5 to bcrypt, making it harder for them to be brute-forced if they are leaked.
