Switching between restricted-access websites on mobile user devices

A non-transitory machine-readable medium carrying one or more sequences of instructions for switching between restricted-access applications, which instructions, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving first access information enabling access to a first restricted-access application;
• granting access to the first restricted-access application based on the first access information;
• storing the first access information and sending a first authentication key authenticating access to the first restricted-access application;
• detecting exiting from the first restricted-access application and receiving second access information enabling access to a second restricted-access application;
• granting access to the second restricted-access application based on the second access information;
• storing the second access information and sending a second authentication key authenticating access to the second restricted-access application;
• detecting existing from the second restricted-access application;
• receiving the first authentication key and a request to re-access the first restricted-access application;
• using the first authentication key to authenticate the first access information;
• and
• granting access back to the first restricted-access application based on the authentication of the first access information.

A method for accessing applications over a computer network, the method comprising:

• receiving a request to access an application;
• receiving access information;
• granting access to the application based on verification of the access information;
• storing the access information and sending authentication data for authenticating access back to the application;
• detecting termination of access to the application;
• receiving the authentication data and a request to reestablish access back to the application;
• using the authentication data to authenticate the stored access information;
• and
• granting access back to the application based on the authentication of the stored access information.
