A user is experiencing issues synchronizing a smartphone.
The user is able to connect to individual services, but each requires a different password.

Click on the arrows to vote for the correct answer
A. B. C. D.D.
The correct answer to this question is D. SSO (Single Sign-On).
SSO allows users to use a single set of login credentials to access multiple applications and services. In this case, the user is having issues synchronizing their smartphone because they have to enter different passwords for each service. By configuring SSO, the user can access web services securely with a unique password, making the process more efficient and user-friendly.
Option A, SIM (Subscriber Identity Module), is a small chip that is inserted into a smartphone to identify the user on a mobile network. It does not have any relevance to the issue described in the question.
Option B, SMB (Server Message Block), is a protocol used for sharing files, printers, and other resources on a network. It is not related to the issue of synchronizing a smartphone with web services.
Option C, SSL (Secure Sockets Layer), is a protocol used to establish a secure connection between a client and a server. It is used to encrypt data during transmission, but it does not provide a solution to the problem of requiring different passwords for each service.
Therefore, the correct answer is D. SSO.
