Cannot sign into Skill Builder with email, password, and MFA

I understand you're having trouble logging into AWS Skill Builder despite being able to access the AWS Management Console with the same credentials. This is a known issue that can occur for several reasons.

Since you're using MFA, one possibility is that the MFA code you're using for Skill Builder might be different from the one for your AWS Management Console. AWS Skill Builder typically uses AWS Builder ID for authentication, which is separate from your regular AWS account credentials.

Here are some troubleshooting steps you can try:

1. Clear your browser cache and cookies, then try again
2. Use your browser's incognito or private mode
3. Try a different browser or network
4. Check if you're using the correct login method (AWS Builder ID vs. AWS account)
5. Verify your device's date and time settings are correct
6. Ensure your MFA device is working properly

If you're still unable to log in, you may need to contact AWS Support directly. For Skill Builder specific issues, you should use the AWS Training support form. If you've lost access to your MFA device for your Builder ID, recovery might be challenging as AWS recommends registering multiple MFA devices to prevent lockouts.

For Builder ID MFA issues, AWS Support may be able to help deactivate your MFA device after verifying your identity, though note that if you've lost access to all registered MFA devices for your AWS Builder ID, recovery might not be possible according to AWS documentation.
