I was trying to use the desktop app and entered in the same email and password I use for the browser version. It said the email and password doesn't match. Can you please look into this?
There can be two cases:
1. You signed up to TMetric with Google account. You need to go to your profile page and create a password for the desktop client.
2. You forgot the password. To check if it's true, log off the main app and try to login again (not using browser password hint).
