Burt has a Motorola Max mobile device and an iPad. He got a notification to update his security and contact list on his phone, but the iPad gave him a notification that his Google password had changed without his knowledge. Leo says that's worrisome. It sounds like someone may have hacked his Google account. Leo advises going to iCloud.com to see if he can log in. If he can, then his AppleID is likely secure. But Leo advises changing the password again to verify everything. He should make sure that he has 2 factor authentication turned on as well. Leo also recommends signing up for LastPass to keep his passwords safe.
