Does the customer need a multi-factor authentication solution?
Passwords are weak. There's no real argument against that statement.
Passwords can be cracked. All it takes is time. Is your customer paranoid? Do they need a more robust authentication solution? Is multi-factor authentication a viable solution for your customer?
Multi-factor authentication products make a lot of sense these days. Common solutions include token and key-based systems, such as random number cards or RSA key tokens. Biometric options also exist that will add authentication based on retinas, fingerprints, voice recognition and facial recognition. All of these solutions have become much easier to use and administer and use a normal username/password combination along with another form of authentication. Users can be assigned a secure card or token, or every client software, that is used to help them log into critical areas based on their job function. Costs are the biggest issues when it comes to multi-factor authentication, but there are a variety of options at varying price points.
