Factory Reset Protection helps keep your data safe if your phone is lost or stolen, so you need to wipe your phone before you sell it.
Factory Reset Protection (FRP) is a security method that was designed to make sure someone can't just wipe and factory reset your phone if you've lost it or it was stolen. Starting with Android Lollipop, FRP is "standard" in vanilla Android, and most companies making our phones have implemented it in their own models. It's a good thing — it makes a stolen phone harder to use, which makes it less appealing to thieves, and anything that can protect our data on a phone we've lost is welcome.
It can become a problem if you sell, trade, or even give away a phone without factory resetting it, though. How it works explains why.
You have to be signed in with the "owner" account of the phone (the one you used to set it up) in order to factory reset it. That means if you give me your phone I can't reset it without you being signed in There are random workarounds on the Internet, but they tend to get patched almost as soon as they are discovered. You'll pretty much need to know the login details for the last account to use the phone before you can reset it and create a new owner account.
We've been bitten by this ourselves. We ship phones all over North America and the U.K. and sometimes it's easy to forget you're still signed in when you stick a phone in a box. And yes, we end up having to share a password to get past the initial setup because of other policies Google has in place to protect your account. If you change or reset your Google account password, you can't use it to wipe a phone that's using it for 72 hours.
Disabling FRP (Factory Reset Protection) is simple. On most phones, it will be automatically done whenever you choose to reset the data through the phone's settings. If your phone has an extra layer of reset protection from the company who built it or has a "find my phone" app from the company who built it, you'll want to disable that manually first.
There may be a few devices still in use that require a bit more hands-on work. If your phone is running Android 5.1.1 you might need to remove the accounts that are signed in manually:
You can make sure any reset protection has been removed from a phone you want to find a new owner for. Just try to sign back into it after you've reset it. If it asks for the previous username and password, FRP is still enabled. If it doesn't you're good to go: power it off and box it up!

- Open your device settings and remove any security you have for the lock screen. This isn't a required step for all phones, but some want you to do this so we're including it here.
- Once that's done, you need to remove any and all Google Accounts from the phone or tablet. That's also done in the settings — look for a section labeled Accounts. With an account selected, look for a delete or remove option, usually hidden behind the three little dots in the top corner of the screen.
- When you've made sure all of the Google accounts have been erased, you can then factory reset your phone or tablet through the device settings.
