Fastmail launches one-time passwords by SMS

Consumer and small-business e-mail hosting provider Fastmail has launched a variety of new authentication mechanisms for its’ products including one-time passwords by SMS – ideal for web access on untrusted computers.  Users pre-purchase credits for SMS (Fastmail already offer mail-to-SMS services) and append the one-time password to a base password, which is pre-configured.  Passwords have a variety of expiry options.

Commercially, this solution has been available for some time from Clickatell and RSA for enterprise customers, but it’s good to see this filtering down to the consumer space.
