HAM - Heyes Authentication Method

Features

• The key is tied to the domain name so browser integration could completely prevent phishing [1]
• User only needs to remember a simple 4 character pin instead of a password
• After 3 failed attempts account will be disabled
• Heyes keys are stored in plaintext so they can be encrypted and stored in a safe location

[1] A firefox plugin could be coded or built into any browser so that the string HeyesKey: is found in the clipboard and tested against the current domain to see if it is allowed.
