This plugin allows you to implement the MyPW One-Time Password system into WordPress.
In the Site Administration section go to "Plugins"
Activate the plugin "MyPW Authentication"
Click on Settings --> MyPW Auth
Select your password method. You have three options:
To associate a token with a user, click on "Users"
Click "Edit" next to a user
Enter the user's token ID in the MyPW Token ID field
Any users who do not have a token specified will just use their standard username and password to log into WordPress.
