Hello Oday,

  It sounds like you're having trouble logging into Odoo. This issue might occur for several reasons, such as a forgotten password or a recent change in credentials. Here's what you can do to resolve this:

  First, try resetting your password using the "Forgot your password?" link on the login page. This requires access to the email associated with your Odoo account.

  If you're an administrator trying to access the database directly, check if the master password has been changed. The master password is required for administrative tasks such as database management.

  If you're still unable to access your account, it might be necessary to contact your system administrator or the person who set up your Odoo instance. They can reset your user credentials directly in the database.
