AbstractDuring the past years we have been witnessing an exponential increase in the use of smartphones. This increased use of smartphones has led to a growing demand and supply of mobile applications: some do not require authentication while others do. For users, having to remember all the passwords and usernames can become a real baffling problem. This problem could be solved by always using the same usernames and passwords for all applications, but it would cause a security problem for users. The challenge here is to allow the user to authenticate into various applications via another application. The use of this application to authentication would avoid some security problems that users might encounter. Indeed, it would reduce the number of aliases and so it would reduce the eventuality of his identity being usurped.
There are already several ways to use this technique as one-time passwords but also techniques of tokens. We will examine the benefits and disadvantages of these solutions and especially the OAuth authentication technique. We will discuss its growing use in the first place and try to understand why this technique is promising if neglected.
