Scenario:
- I create a new IAM user and choose "AWS Management Console access" for "Access type".
- For "Console password", I choose "Custom password" and set a password.
- I attach a policy to the user allowing full access to all AWS resources.
- I log out of the console.
- Then I go to https://$MY_ACCOUNT_ID.signin.aws.amazon.com/console. I enter my Account ID, IAM user name, and password. Every time I try logging in this way, I get a message that says "Your authentication information is incorrect. Please try again."
However, if I create another IAM user and choose "Autogenerated password" instead of "Custom password", I can log in with this user.
I've tried selecting different options when creating the user, but the only difference between it working and not working seems to be choosing "Autogenerated password" instead of "Custom password".
Am I doing something wrong? This answer is the only related info I could find.
