There are plenty of ways to protect your phone and the information it has from any unwarranted access, this can be done in the form of numerical passwords, alphabetical passwords, pattern locks, and more. Over the years of Android’s development, new methods have been developed in order to make this more secure and advanced, but a lot of people still prefer the traditional methods.
The same can be stated for the Samsung Galaxy S9 and Galaxy S9 Plus where a lot of owners still prefer the more traditional passwords methods for their phone’s security despite the phone model’s new and improved features. Problems arise when people sometimes forget what their passwords are, this is even more common for pin passwords compared to pattern locks or words.
Indeed it is quite an ironic predicament that you are here since your pin password is supposed to keep out other people from accessing your phone, and now you are the one being barred access. You don’t need to worry too much as this situation is not permanent and there are several ways to deal with a forgotten pin password. It is worth noting that this article is not just for solving your issue with the pin password but also for making sure that it does not happen again, or that if it does, you will know what to do.
Right now there are three good solutions which you can choose, two are safe but require prior registration to certain services, and one is quite drastic and costly, in terms of effort at least. The latter one is the dreaded hard factory reset  which will be discussed later and can be troublesome for a lot of phone owners.
For now, you will have to deal with the first two safe solutions before even considering that factory reset. Hopefully you have set up the necessary prerequisites for both solutions.
What to do if you forget the pin password for your Samsung Galaxy S9 or Galaxy S9 Plus:
Take note that these solutions will basically give you access to your phone alternatively, enabling you to change its password or security measure without having to deal with the lock screen. You should follow them carefully, though there are certain requirements for the first two.
Use Samsung’s Find My Mobile
For those of you who had an iPhone before and registered the device to Apple, you might find this procedure familiar. This is quite similar to Apple iCloud’s Find my iPhone. As with both services, the users would need to have had registered his or her device to the website for them to be able to take advantage of it. So if you did not register your Samsung Galaxy S9 or Galaxy S9 Plus, then you might want to skip this step.
If you cannot recall doing so but might have, then we advise that you still try this anyway since you could have registered your device in the past but just forgot about it. This also requires another smartphone or computer that you have access to since you will be visiting a website.
- To Begin, have your locked phone nearby
- Turn on another smartphone or computer in order to access Samsung website
- Go to Samsung’s Find My Mobile website right here
- Sign into the service
- Select the Remote Control feature in the Find My Mobile service
- This can be used to reset your phone’s password, for now give it a temporary and easy password
- Once your password is ready, unlock your phone and enter the temporary password
- Once you have access again, quickly change your phone’s password or security measure to something you will not forget in the future
Bear in mind that this might need your locked phone to be connected to a network, which can be unfortunate for users who regularly turn off their Wi-Fi or Mobile Data for their phones. Now if you find that your are not registered to Samsung’s Find my Mobile service, move on to the next procedure below.
Use Android Device Manager
This also might require your phone to be online and also requires a computer, the difference is, instead of using Samsung’s service, you will be using Google’s. Though this should be easier since Android Device Manager  sometimes automatically registers the device as long as you have a Google account on your phone.
All of the phones you’ve registered in the past appear here. Only ones that are active right now are accessible though. This is also handy for keeping tabs on your android devices. If you have many, it shows the dates of registration and when they were last online.
- Register your device to Android Device Manager. Your phone might already be here if you logged in your Gmail or Google account
- You’ll need a computer again with this one, so have it at the ready
- Go to the Android Device Manager in order to start
- The website will ask for your Google credentials, enter them and check if your device is on the list of registered ones
- Select the lock feature on the left side of the UI
- Follow all the succeeding steps until you come upon creating a new temporary password for your locked phone
- Use one that is easy to remember for now
- Unlock your phone and enter your new password
- Once you have access again, replace the old password or security feature with one that you can easily recall
Now this will only work if you have a computer or have registered your device to Google. This is highly possible since it is one of the first protocols a phone requires you to do. However, there might be some instances where this is not available to you. If that’s the case, then proceed to the last and final step below.
Do a Factory Reset
Unfortunately if none of this has worked so far, your phone’s security is most likely unbreakable. Your only solution in that case is to factory reset the phone, sacrificing your personal data in the process. This is the so-called factory reset option. It will erase your phone’s password, along with everything else in your phone. So don’t take this step lightly.
Basically you will have to reset your phone to a state when it was first sent from factory. This will essentially erase all the information and user data you placed in the device. This includes photos, videos, apps, updates, documents, contacts, messages, and everything you stored on the phones drive. The tedious part about this is that you’ll have to enter all of your settings again. If you also have some important data you don’t want to lose, this step might not be best.
- Turn off your locked phone by pressing and holding the Power button until it shuts down completely
- Once it is off, press and hold the Volume Up, Power, and Home/Bixby buttons all at the same time
- Keep holding all three buttons until a Samsung logo appears and the phone vibrates
- If you see an Android logo with the words “no command” on the screen, tap anywhere to go past it
- You should now come across the Recovery Mode of your phone
- Be careful not to activate anything unnecessary there since you might change your phone unexpectedly and unwittingly
- You can navigate using the Volume Up and Down keys
- For now, use the Volume Down until you have selected or highlighted the Wipe Data/Factory Reset command
- Confirm this option by pressing the Power button
- Your phone should now undergo a full factory reset. Wait for it to finish as it may take a few minutes depending on the amount of stored data
- Then, the phone will turn off. If it does not restart by itself, turn it on manually
- Your phone should now be free of any password. We advised that you still set up a security feature. This time make it more accessible to yourself
