Authentication code mail is not coming.

I didn’t get the authentication code that was displayed when I logged in with an existing account.

Usually, when you change your password, you receive a password change email.
However, no authentication code mail will be sent.

You should remove your personal email. This is a public Community. Also the photos have personal information that doesn’t need to be posted.
