Abstract
A system and method for facilitating users to obfuscate user credentials in credential responses for user authentication are disclosed. A string sequence may be presented to a user for prompting the user to input credential characters sequentially but not continuously. The string sequence may comprise a set of prompt strings containing a prompt character sequence associated with the user and a set of noise strings that do not contain the prompt character sequence. The individual prompt strings in the set of prompt strings may be composed by obfuscating the prompt sequence among noise characters. A user credential response may be received and a user provided credential may be extracted from the received user credential for user authentication.
