Android 8.1 brings a lot of exciting options and features, but it also comes with a serious limitation. Forgetting your PIN or password will lock your phone. With Android 8.1, it will no longer be possible to bypass the protection of a device if you don't know the PIN, password, or pattern. This measure adds another layer of security against those who want to hack your phone.
It should be noted that this feature is not new to the market. We already see it on iPhone devices, but we are definitely talking about a practice that has either fanatical fans or fanatical haters.
Although this is a controversial type of security, it is certainly quite useful. Users who forget their password may be at a disadvantage, but it ensures the security of your mobile phone from any kind of trick.
The only unfortunate thing about this is that Google didn't warn users about the new Android 8.1 modification, so many of them were caught by surprise. Although the feature is still in Preview, many were already using it.
It was found that if you do a factory reset, you will not follow the same steps to set up your device but will need to know your password or PIN or pattern.
Also, downgrading to an older version of Android doesn't change things, so there's no way to get rid of this protection method. It may be possible to boot into TWRP - if, of course, the bootloader was unlocked from developer options - if not, you'll have to turn to Google for help.
