CustomAuthStart Event

Reports the beginning of a custom authentication method.

Syntax

type TCustomAuthStartEvent = procedure (
  Sender: TObject;
  const UserID: String;
  const AuthMethod: String;
  var AuthMethodPars: String;
  var AuthMethodData: String
) of Object;

property OnCustomAuthStart: TCustomAuthStartEvent read FOnCustomAuthStart write FOnCustomAuthStart;

Remarks

This event marks the start of an authentication method not supported by component internally and requests authentication parameters from the application.

Component currently supports the following authentication methods:

• password
• otp-h
• otp-t
• dcauth

The application may also use any number of custom authentication method it wants. Each such method is identified by a unique string name (such as 'pin', 'fingerprint', or 'fingerprint-v2'). It may specify them in DefaultAuthMethods property, or provide on the fly via AuthStart event.

The event handler may return authentication parameters and application-specific data to be associated with the authentication attempt via AuthMethodPars and AuthMethodData parameters.
