Error: "The user name and password are incorrect." when opening a company.

How to solve the error: "The user name and password are incorrect. Please enter a valid user name and password" when opening a company file.

Cause

Incorrect or forgotten username or password.
Sage 50 only allowed 7 characters in 2022 and older but users are able to assume the password is longer than seven characters.
Issues with database.

Option 1: I was able to login with sysadmin with 2022 or older but not 2023.0

Enter sysadmin as the User Name:
Enter only the first 7 characters of your known Password in the 2023.0 version.
- To avoid password confusion, you can also change your password to 7 characters or less in the 2022 version by following How to change or delete a user's password?
- Enter your new password for sysadmin when converting to 2023
- After the file is opened in the 2023.0 version, you can follow How to change or delete a user's password? again to ensure the password is longer than 7 characters

Option 2: The error still occurs after entering my known sysadmin password

If your system administrator does not know the password, contact Customer Support at 1-888-522-2722 for a password reset.
- If the password reset does not work, restore from a recent backup to a local drive by following How to restore from a backup.

Option 3: I can login with sysadmin but not with another username

Login to the company using sysadmin as the username.
Select Setup, then Set Up Users.
Type the sysadmin password.
Select OK.
Select the User, then Modify.
Enter the Password, then Re-enter Password.
- The password limit is 7 characters in 2022 and older
- The password can be longer than 7 characters in 2023.0 and higher versions
Select OK.
Select Close.
