What should I do if I'm having trouble logging in to PassWatch via the Windows browser?

You are unable to log in to your PassWatch account due to the following reasons: 
1. Incorrect PassWatch Account mail address
2. Incorrect Master Password
3. Incorrect 6-digit code and Two-factor authenticator code
So please check all the above factors and try to figure out the actual reason first.

Next, try using the PassWatch recovery options. Ensure you're entering the correct credentials, and consider resetting your master password if needed. Keep your master password secure and avoid sharing it with others.
