DigitalFortress Private Limited is a startup that is focused on developing innovative authentication technologies that do not require traditional passwords or physical contact. Passwordless authentication refers to the use of methods other than a traditional password for verifying a user's identity. This can include techniques such as biometric authentication (e.g. facial recognition, fingerprints), token-based authentication (e.g. security keys, one-time codes), or behavioral authentication (e.g. typing patterns, gait analysis). Touchless authentication refers to methods that do not require physical contact, such as facial recognition or voice recognition. By focusing on these types of authentication methods, DigitalFortress Private Limited is likely aiming to provide users with secure, convenient ways to access their accounts and systems.
