ETDA Any Where is the application that uses your mobile phone to connect to ETDA services. ETDA Any Where enables password logins to be replaced with an easier and more secure authentication mechanism. ETDA Any Where provides a strong authentication by using an asymmetric key to sign a digital signature on a challenge message with an enrollment server. You can register your phone via a provided website and use your phone to log in to your ETDA application services instead of using a password. Using ETDA Any Where, you can simply authenticate to ETDA application services by using existing phone verification mechanisms e.g. fingerprint, Face ID, or PIN. ETDA Anywhere can be used for signing documents with a digital signature which uses the same mechanism as the authentication method.
