Visual Hashing works by displaying colored boxes as you type on the password field. Different passwords will also have unique color combinations. If you type the password long enough, you should be able to remember the color combination and later notice if the colors are off if you misspelled your password.

Features:

• Extension for Chrome and Firefox.
• Prevent misspelled password with color cues.
• Remember color cues before clicking log-in.
• Needs to be used a lot to be very useful.
