Use OAuth such as Google, LINE to login and register.

Use Oauth such as Google and LINE account to login, register member in WordPress website.
Both Google and LINE already have “Multi factor” or “2 factor” authentication. 
So, instead of implementing the 2FA (2 factor authentication) into your WordPress and add those keys into your user’s authenticator app on smart phone (which may already have a lot of them). Just use OAuth system!
It is very easy and much secure for your users on your WordPress website. (Depends on your user security settings on those providers). 
Since v 1.0 your users can register using OAuth in one click from your website and one click to allow/continue on OAuth provider website.
You can also change login expiration by using remember login. 
You can set how your user login use OAuth with normal login form, or OAuth only, or disable OAuth login from Rundiz OAuth settings page.
