Abstract: The internet has one of the most convenient and widely used media for people for exchanging information and to do business over the internet. E.g. Accessing web based emails, online auction or banking sites. But now a days accessing the internet is faced with many challenges. One of the most popular challenges is to ensure security with vital role to provide security in websites. Text password is a convenient and simplest form for a user authentication on websites, and it is level to security attacks. User mostly used weak password and it is often used across several websites and reuse password by typing into untrusted websites causes password threats. Hackers launch password stealing methods to grab password such as phishing, malware, and key loggers. The proposed system is a user authentication protocol named LOPass which creates long term password and one time password for authenticating the user. It uses three phases as registration, login and recovery phase. Here random password is generated for each login. Registration is used to register the user. Recovery phase is used, if the users mobile phone gets lost. The user needs remember only his long term password which has been stored in database very secretly and securely.
