Turning off less secure app access to G Suite accounts - Impact to Contacts

Limiting the ability for less secure apps (LSAs) to access G Suite account data. If your G Suite account is syncing contacts to iOS or MacOS via CardDAV and uses only a password to login, you’ll need to remove your account. When you add it back, select “sign in with Google” to automatically use OAuth. If your G Suite account is syncing contacts to any other platform or app via CardDAV and uses only a password to login, switch to a method that supports OAuth.
