I am using a computer in a different office (Location B) that is not accepting my user name and password that I use from my computer in my office in (Location A)
Possible Reasons this happens:
Here are some reasons you maybe have problems.
1) Passwords can only be changed by the Super Admin. If your password was changed by a Super Admin then anywhere you sign-in would be blocked if you didn't know your new password.
2) Another reason and more likely - The password used on the computer browser at location A is set up to auto-fill (remember) your password. This is a convenient option to use but can cause problems when you travel to multiple sign-in locations. When traveling to the other location you may be required to type in your password if you set up the browser to remember it. Important reminder passwords are case-sensitive
Contact your Super Admin in your organization to change your password.
