Stored procedures
Verifies the code given by an authentication application.
Example
IF TwoFactorAuthenticationCheckCode(nCode, sTOTPKey) = False THEN
Error("Invalid code.")
RETURN
END
Syntax
<Result> = TwoFactorAuthenticationCheckCode(<Code> , <TOTP key>)
<Result>: Boolean
  • True if the code is valid,
  • False otherwise.
<Code>: Integer or character string
6-digit code generated by the authentication application.
AndroidAndroid Widget This parameter must be an integer.
<TOTP key>: Character string
ANSI string that contains the TOTP key of the user to be authenticated.
Remarks

Validity period

  • The code validity period is slightly longer than the period shown by the authentication application. For example, when Google Authenticator shows a new code, the previous code is still valid for 1 minute.
  • TwoFactorAuthenticationCheckCode checks the codes generated 1 minute before and 1 minute after the verification request is made.
  • WEBDEV - Server code For a website, make sure the UTC time of the web server is correct. The server that hosts the website may be in a different time zone than the users of the site, but the server and the devices must use the same time.
