Abstract
A method and system for verification of a pattern based passcode. A user input of a series of key inputs is received. A registered pattern for the user of a sequence of keyboard direction movements is retrieved. A first character input in the series of key inputs is identified. It is determined that the identified first character is not in an excluded group of characters, wherein the excluded group of characters are previously used first characters in a defined period or number of instances for the user. In response to having determined that the first character is not in the excluded group of characters, the series of key inputs after the first character input is compared with the registered pattern for the user.
