FAQ
-
Does this replace password login completely?
-
By default, no. OneCode Login works alongside traditional password login. However, you can enable the “Replace wp-login.php” option to use OneCode Login as the primary login method.
-
What happens if the email does not arrive?
-
Users can request a new code after the cooldown period (default: 60 seconds). Check your server email configuration if emails consistently fail to deliver.
-
Is this secure?
-
Yes. The plugin uses cryptographically secure random number generation, time-limited codes, rate limiting, and request binding to prevent various attack vectors.
-
Can I customize the email template?
-
Yes. Go to Settings > OneCode Login > Email tab to customize the subject and body of verification emails. You can use placeholders like {code}, {expires}, {site_name}, and {user_email}.
-
Does it work with multisite?
-
The plugin is designed for single-site installations. Multisite compatibility may be added in future versions.
-
What if a user does not have an account?
-
The plugin only allows existing users to log in. For security reasons, it does not reveal whether an email address has an account – users always see the same “check your email” message.
