Why not use more secure password

Is there any reason not to use the more secure password format? I don’t have any custom code anywhere that accesses the Internet password. If I turn this option on, will there be any effect on the users?

Thanks

The only reason to use the old internet password hash format is if you have applications that are hard-coded to use the old @password format. Since we added the more secure format in 4.6, hopefully there aren’t too many apps left that haven’t been updated to the new format. And if you don’t have any custom code anywhere that accesses the http password, you’re definitely safe.
