Disclosed is a technique to indicate whether a newly chosen password is easy to type, easy to remember, and fast to type, on the basis of certain factors. This article covers: 1) A technique that indicates to the user whether the newly selected password is easy and fast to type, based on the keyboard pattern of laptops, smartphones, tablets, and other input devices. 2) A technique that indicates to the user whether the password is desirable in many senses - namely, that it's strong, easy to remember, and easy to type. 3) A technique that suggests variations to a user selected password to make it more desirable as per the characteristics specified in #2 above

Informing the user if a newly chosen password is fast and easy to type


When choosing a new password with current systems, a user may choose a password that is strong and secure, but at the same time compromise on the ease of typing it, and therefore the speed.

Current method

There exist password mechanisms where one chooses a new password and the system indicates whether the password is strong or weak as shown in Figure 1 and 2 below. But the user does not get to know how complex the password is in terms of typing and remembering.

Drawbacks of the existing solution

As the existing mechanism only indicates whether the new password is strong, and not whether its easy or fast to type based on the keyboard layout, it has the following drawbacks:

The password can often be too complex, requiring some effort to type

The user might end up mistyping it too often The chances of a shoulder surfer watching what the user types might increase, because of the user's slow typing speed


Based on the device from where the user is entering a password, the system will calculate the possible speed at which it can be typed, and compare it against passwords of similar length to provide an indication of relative speed. It will also suggest the relative speed at which it could be typed on other devices.

For example, adjacent letters in the password that are on opposite ends of the keyboard can be typed by different hands, and hence can be typed faster than adjacent letters which belong to the same side. Also, letters than form common sequences in the language (for example, "the" in English) can be typed much faster than uncommon sequences.

In addition to the above, the system will also indicate whether the password is strong enough in the traditional sense, and also whether it is easy to remember. As an example, passphrases, which are passwords that consist of multiple words, are both easy to remember and strong.

The system can suggest better passwords which are easier to type, and easier to remember too. Also, the user may want to try out an altogether different password to get a better score on all the three parameters.

Implementation Steps

User enters a new password in the new password text box the speed and text will be



User enters a new password in the re-type new password text box the speed and


text will be recorded

The following statistics will be calculated:


The comparative typing speed of the password in the two password fields


The number of characters


The ideal speed that the password should be typed at


The user's average speed


The presence of easy words


The keyboard pattern of the device being used

Other than the above, one can consider if the user had to do any corrections in the new and retyped password fields, possibly due to a very long password or due to difficult, unusual words. This wo...
