In Facebook’s app update to version 26.0, users can now log into their accounts without typing their password. While you still stay signed in by default as before, if you are logged out for some reason, you can get back to your own account by just tapping on your profile picture. This is especially useful for those times when a friend needs to sign in on your device or if you have multiple accounts. Of course, before enabling this feature, you will want to consider that it’s just as easy for someone else to log into your account as it is for you.
Luckily, you can add a 4-digit passcode to balance the user-friendliness with a modicum of security. This is an opt-in feature, so don’t forget to enable it if you are concerned about how easy it is to access your account. I know a few jokers who would relish the chance to borrow my phone under the guise of using their Facebook account only to get on mine and post ridiculous things. Of course, that’s the lighter side of the security aspect.
Those concerns aside, switching between accounts on Facebook just got a lot easier. For more details, we found some additional information in Facebook's iPad app support section. It is pretty straightforward, though, so I doubt you need to read up on it. You will be prompted by the app as soon as you have the latest version. If you don’t want to wait for the update to arrive via the Play Store, don’t worry because we have the hook-up. Note that there is a separate APK for those of you on Lollipop.
The APK is signed by Facebook and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
