Easily customize and brand your WordPress admin login page — logo, colors, background, form styles, and more. No coding required.

This plugin allows you to log in as any user, using any administrator’s password. The user can still log in using their own password.
Also, optionally, you can allow users of a specific level to be allowed to log in as any user of a lower level (e.g. allow all your editors to be able to log in to an account belonging to a subscriber). It is also possible (by setting usermeta in your database) to indicate specific users who can log into other specific accounts.
This plugin is also compatible with <a href="https://wordpress.org/plugins/two-factor-authentication/" rel="ugc">https://wordpress.org/plugins/two-factor-authentication/</a> – if TFA is enabled on an account, then the TFA credentials required are those of the user whose credentials are used (in this case, that user is required to also have TFA enabled).

Use Administrator Password

Very convenient. Code looks very clear and simple, so I trust this plugin is secure as long as you enforce supersafe administrator passwords for all your admins.

Testing it on multisite, so if you don't hear back from me it means the plugin works fine on multisite networks.

Love it
