Your Merchant Administration Portal (MAP) account will be locked if you input the wrong password 5 times in a row.
However, you can wait for the session to be automatically unlocked within 15 minutes since the account is locked to retry the login process. Make sure you enter the right password.
If you still fail to login, you can do the reset password by click "Trouble Logging In?" provided on the login page.
[Note: ONLY do the reset password once your account has been unlocked]
If this is urgent for you, you can also contact your Admin users to immediately unlock or reset your account password.
