In order to facilitate use when needed, the network application information can be stored in a cloud server. [0003] Currently, users need to manually enter a preset account number and password to log in to the cloud server and use the network application information in the cloud server. However, manual input is likely to cause inconvenience to the user, especially when the preset account number and password require special symbols or case switching will aggravate the difficulty of ...

AI Technical Summary

Problems solved by technology

However, manual input is easy to cause inconvenience to users, especially when the preset account number and password require special symbols or switch between upper and lower case, it will aggravate the difficulty of user operation
