Hey there! Nice to meet you!
Unfortunately, it is not possible to update the account’s security information without successfully recovering the account or gaining access to it.
Just to confirm, did you have two-factor authentication (2FA) active on the account?
Important: If you have an active 2FA, ACSR will inform you that your recovery request will be ignored. If you only receive a message that the recovery request is either successful or indicates insufficient information, this means that 2FA is disabled.
Also, may I know when was the last time you successfully signed in to your account?
Best regards,
Darhyl
