Improve the security of your WordPress by using the One-time Password feature of WP OTP: <a href="https://wpotp.com/" rel="nofollow ugc">https://wpotp.com/</a>
WP OTP is an external service and you must create an account (which can be created from WordPress) to use the plugin. You only have to provide an email and a password.
Once the plugin is configured, an SMS will be sent to you at your next logins to authenticate yourself.
By adding this extra layer of security, it’s much harder for hackers to break into your accounts.
<h4>User-specific</h4>
Each user can have their own number and the 2FA feature does not have to be enabled for all users.
