Cognitive password pattern checker to enforce stronger, unrepeatable passwords

A computer system for determining a password strength, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• receiving a user-entered password;
• identifying a keyboard layout type associated with a keyboard utilized to enter the received user-entered password;
• mapping each character within a plurality of characters in the received user-entered password to a corresponding location on a grid associated with the identified keyboard layout type;
• determining a coordinate sequence associated with the received user-entered password based on the mapped plurality of characters;
• applying a pattern recognition algorithm to the determined coordinate sequence;
• determining a password strength based on the applied pattern recognition algorithm and comparing the determined coordinate sequence of the received user-entered password with a previous password coordinate sequence, wherein the determined password strength will be weak when the determined coordinate sequence is the same as the previous password coordinate sequence;
• and
• displaying the determined password strength to a user on a graphical user interface associated with a user device.

A computer program product for determining a password strength, the computer program product comprising:

• one or more computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:
• program instructions to receive a user-entered password;
• program instructions to identify a keyboard layout type associated with a keyboard utilized to enter the received user-entered password;
• program instructions to map each character within a plurality of characters in the received user-entered password to a corresponding location on a grid associated with the identified keyboard layout type;
• program instructions to determine a coordinate sequence associated with the received user-entered password based on the mapped plurality of characters;
• program instructions to apply a pattern recognition algorithm to the determined coordinate sequence;
• program instructions to determine a password strength based on the applied pattern recognition algorithm and comparing the determined coordinate sequence of the received user-entered password with a previous password coordinate sequence, wherein the determined password strength will be weak when the determined coordinate sequence is the same as the previous password coordinate sequence;
• and
• program instructions to display the determined password strength to a user on a graphical user interface associated with a user device.
