WebTech360 - Applying Passcode in the process of securing Android or iPhone mobile devices is much more effective than what users think. But what if the user accidentally forgets this Passcode string? In the following tutorial, we will introduce you to some basic steps to fix this problem with Android and iPhone smartphones .
For Android phones:

Use Google's official support option:
Fortunately, this operating system platform has a built-in problem-solving mechanism, all we have to do is enter the wrong Passcode 5 times in a row. Then, the system will display the “ Forgot Passcode ” function button or similar in the form of a pop-up, then you will be transferred to the function department to manage and edit personal account information related to Google, and finally request to create a new Passcode . And this time, please try to remember this information.

Using Screen Lock Bypass utility :
However, the method presented above by Google still has some shortcomings from the past, which is stability and the results brought to users are not really as expected. Therefore, application developers have created and announced the Screen Lock Bypass application , with the function of being able to "bypass" the LockScreen protection mode every time the user activates it, so there is no need to enter the Passcode as before. Of course, this application does not completely remove the Passcode but only temporarily "skips" this user confirmation step. Therefore, you should only use this utility in temporary cases, after accessing the phone, you must delete the old Passcode or change it.
All you need to do is access the above link, download and install Screen Lock Bypass on your device as usual, then continue to install any application so that Screen Lock Bypass automatically activates, and this utility also automatically starts every time the user reboots their device. Once again, you will need to use Google's account recognition function, so outsiders or thieves will find it difficult to apply this method to illegally access your device.
For iPhone:

In fact, there are many methods that are compiled and freely shared by the user community on the Internet, but most of them are not as effective as they expected. For some old iOS versions, there is a fairly quick method, which is that users just need to create a "fake" emergency call to be able to access the system normally. However, this method is no longer effective. Another way is that users can delete the passcode file in the iPhone's root partition folder using iExplorer, iPhone Browser, or access the jailbroken device via SSH protocol, and this method is no longer effective.
And by inference, resetting the entire iPhone will be a sure way to erase all the Passcode or access password that we have forgotten. But if you just do it the usual way, it will not be effective because the Passcode will block the user right at the beginning. To fix this, please follow the steps below:
- No matter how locked your phone is, it can still connect and operate with your computer. Do this first to back up your data via iTunes , if you use iCloud, you may want to transfer that amount of data to your personal computer to ensure safety, in case of any risks that may occur at any time.
- Switch the iPhone to DFU mode - Device Firmware Upgrade . To do this, restart the phone by pressing and holding the Power and Home buttons at the same time for about 10 seconds. Until we see the Apple logo, release the Power button but keep holding the Home button, then the USB cable icon will appear, the iTunes icon along with the message: “ Connect to iTunes. ”
- In case you still connect your phone to the computer while iTunes is open , the system will notify that iTunes has detected the iPhone in Recovery mode and needs to be restored. Click the Restore button in iTunes and wait for the iOS operating system to download the necessary files, and finally install it directly on the iPhone :
- The final step is to sync all previously backed up data via iTunes.
Good luck!
