Firebase rules provides a way to identify user role while performing read and write operations. These rules will acts a security layer on the server before perform any CRUD operation. By default the rules allows user to perform read & write operation only after authentication. The below rules allow authenticated users only to read or write data.Write a rules to validate the username to be less than 50 chars , mobile number and email to be valid using email regular expression?

1) Update your SQL server to allow mixed authentication mode. You can do it in SSMS or by running the following TSQL code: use master; EXEC xp_instance_regwrite     N'HKEY_LOCAL_MACHINE',     N'Software\Microsoft\MSSQLServer\MSSQLServer',     N'LoginMode',      REG_DWORD, 2;

End-to-end encryption could be a problem for application-level proxies. Please offer a method for handling encrypted payloads via an application-level proxy.
