`withPassportData(passportData: String)` | Passport serial number or PINFL data | Optional
`withBirthDate(dateOfBirth: String)` | Date of birth. Format: `dd.MM.yyyy` | Optional
**Note 1.1.** You can customize the screen for entering passport data and date of birth in your
application, in which case you can pass these parameters during initialization to the SDK, otherwise
the SDK requires the input of passport data and date of birth for user identification.
**Note 1.2.** If the `sdk_hash` is empty, blank or string with length other than 32 has been
provided, we will continue showing the credentials screen.
**Note 1.3.** If the `externalId` is not empty, has a length of 36 characters and corresponds to the
regular expression UUID4, we will not display a [recommendation](images/screen01.jpg) screen. If a certain number of unsuccessful identification attempts (currently set to 5) occur in MyID within one hour and the `externalId` is not empty, SDK returns to the parent app error message or TTL as `message` in `MyIdException`.
