HBO Max requires passwords to be unique , at least 10 characters long, and with no more than 4 repeating characters in a row. It also recommends not reusing a password from other sites or apps.

Password rules

  • At least 10 characters.
  • No more than 4 repeating characters in a row.
  • Unique to HBO Max; do not reuse an old password from another service.

Extra security tips

HBO Max also advises changing your password periodically and keeping your account email correct and secure.

Example

A password like BlueRiver!482 would fit the length idea and avoids obvious repetition, while something like aaaaa12345 would not because it repeats the same character too many times in a row.
