Is it safe to approve eight characters on the mobile phone?

This should be safe. If you are afraid of insecurity, you can install Tencent Mobile Manager to set up security protection. It has comprehensive functions and good compatibility. It can protect all mobile phone software and files, fully protect mobile phone security, automatically update software, clean up junk cache, uninstall redundant installation packages, save mobile phone memory, and directly organize files and photos, which is convenient and refreshing and makes the mobile phone healthy. Mobile phone acceleration, anti-virus cleaning and so on are all good.
