Many websites and third-party apps will ask for permission to access your Google account for a variety of reasons. They will request different levels of access, ranging from basic profile info used to "sign in with Google" (similar to sign in with Facebook) up to full access to view and edit all data and even create content, which is a scary prospect. It should be obvious by now that you need to take great care regarding your data privacy, so you should know how to see who you've given access to, and how to revoke it if need be. Here's how to do it from your iPhone or iPad:

The PlayStation 4 has been updated to support remote play on iOS devices. This allows you to remotely play compatible PS4 games on your iPhone, iPad or iPod Touch. Games can be played over Wi-Fi using the on-screen buttons. Unfortunately you cannot use the DUALSHOCK 4 with remote play.

Gmail offers a lot of interesting features such as Smart Replies, Undo Send and more, but it can be a bit confusing at times. Sometimes features work across different platforms and sometimes they don't. If you set up a personal signature on your laptop it will not appear in emails within the app and vice versa. You can also not see your signature while writing an email in the Gmail app, but you can on the desktop version. You will need to set up your signature separately within the app and at gmail.com if you want it to appear while switching platforms. Here's how:

Nothing is worse than forgetting an important password. Except maybe forgetting all of your sign in credentials completely. Without the email address associated with your Apple ID, the account cannot be accessed. The good news is Apple makes it possible to look up a lost Apple ID. In the worst case scenario, finding a forgotten Apple ID takes trial and error.

The iPhone, iPad and iPod touch remember Bluetooth devices forever after the first pairing. For iOS users with a long list of Bluetooth devices, it might be time for some house cleaning. Removing old or unused Bluetooth devices from Settings can reduce confusion and simplify your life. Once paired, a Bluetooth device can easily be removed.
