Hello,
I am desperate. I just changed my house router and, with that, the IP address of the Home Assistant installation. As a result, all my Home Assistant clients got logged out. Trying to access, when asked for the MFA, the code is always invalid. Any clues on how to start troubleshooting?
Thanks
Change IP back to original
If that not work, may need to setup all auth/user again
I Forget how MFA is setup but maybe removing that requirement from config is enough to allow user/pass only login
I was trying to remove the files from the folder, the problem is that I don’t have a linux device to edit the USB, and the one mention in the “I am locked out!” guide only points out a read-only way for windows.
The IP thing did not work either 
If none of the other options linked above work, including using SSH and plugging in a keyboard/monitor to the machine you are running Home Assistant on and accessing the console, you might want to just install linux alongside windows on one of your existing machines. From linux you can easily access and edit the files on the USB.
I managed to do it from an old RPI1 that I had without use. Now half of the things are not working properly, but patient 
Thanks!
