"Invalid login attempt" when connecting with Access Token

AI generated answer (using internal Slack threads):

Based on the conversations, the "Invalid login attempt" error when connecting with Access Token can be due to several reasons: 1. Deprecation of HMAC-SHA1 for Token-based Authentication (TBA): NetSuite has deprecated HMAC-SHA1 for TBA. If you're using HMAC-SHA1, you might want to switch to HMAC-SHA256. You can find more details about this in the NetSuite Help Center [here](https://system.na0.netsuite.com/app/help/helpcenter.nl?fid=section_158921905537.html#section_160335709872). 2. Employee Record Issue: Sometimes, the issue can be resolved by editing the employee record and hitting save again. This might refresh the access token associated with the employee record. 3. Revoked Access Tokens: If you have revoked access tokens but they are still trying to login, it can result in hundreds of failed login attempts. In this case, you might need to uncheck the access box on their employee record or remove their email. Also, ensure that the integration on the other end is deleted if the 3rd party site token is still being run. 4. Login Audit Trail: If you're suddenly getting invalid login attempts on your scripts, you might want to check the Login Audit Trail for better error details.
