createAuthenticator

Future<Authenticator> createAuthenticator(String id,
                                          OtpKey otpKey)

Creating authenticator from user id and key.

Parameters:

id - id user.

otpKey - key of user used for auth.

Returns:

Authenticator an object containing all the necessary information to authenticate a user.

generateUri

String generateUri(OtpKey otpKey,
                   String issuer,
                   String user,
                   String label)

Creating URI for register in key in user device.
