If you lose the password for an encrypted Time Machine backup disk, the contents are effectively lost forever. When a Time Machine backup is encrypted, the encryption process secures the data against unauthorized access. The only way to access the data on that backup is through the correct password. Without this password, there are no built-in system tools or recovery methods available that would allow you to regain access to the data. This security measure is designed to protect sensitive information, ensuring that even if someone were to gain physical access to the backup disk, they would not be able to read or restore the backups without the password.

Since the encrypted backup is designed to be secure, other options such as requesting a password reset, recovering data using system tools, or accessing it from another Mac are not viable solutions. The encryption directly ties access to the password, making it impossible to recover the backup without it.
