What is the new login URL after activating WPCERBER?

Hello, This is a recurring problem on a number of my Wordpress installs: once I install WPCERBER the old login URL fails to work anymore, and I have to go into Admin through a backdoor provided by my hosting provider. It works but it's a pain in the ass to navigate through all the extra steps. 1) The domainname.com/wp-admin/ URL which SHOULD work, doesn't. 2) I have not set up any custom login page in WPCERBER 3) SOMETIMES (not always) if I leave the META widget showing on a site, the Login link works okay, instead of having to use the backdoor. But usually it doesn't work either
