Upon logging in for the first time, a message saying "Please change your password" is shown and I cannot log in with the password I set in the beginning.  How can I log in without changing my password?

When your admin is requesting you to change your password, or when the password you have originally set does not meet the security standard, a message saying “Please change your password” appears on the screen.

Please follow password-making rules shown on the screen as you change your password.

After the password change process is complete, you can log in with a new password.
