Google’s Advanced Protection Program is designed to be the ultimate in account security. It’s not something wed recommend for everyone, or even for most people. It makes logging into your Google account more difficult, especially on devices youve never used or use intermittently. Activating the feature also means third-party apps are limited in terms of the data they can access from your account. If you rely heavily on apps that arent actually made by Google, its a good idea to check for compatibility with the feature before you turn it on.”]
