How can I bypass the password on my laptop and tablet?

I have a laptop and two tablets lying around at home that I can't access because I forgot the passwords. I've tried everything, but they won't open.

When I asked my father how I could work around this, he said that the laptop had to be "reformatted" and that he couldn't do it at home.

Is there another way and if not how can I reformat the devices. Do I have to see a specialist or can I do it myself?

When you format the laptop, the memory is reset to zero.

Then EVERYTHING is gone: your password and your data.

So think about it carefully!

Thank you for your answer. 😊

Laptop if windows is running on it you can bypass the password with system rights dzu search in Youtube simply windows 7/8/10 (whichever you have) bypass password

And I can't say much about the tablets because I don't have any information about the device and the operating system. With Windows tablets you will be able to do the same thing as with the laptop. With Android you need a program called "adb sideload / fastboot" and the login password can be accessed via it can be changed / deleted but which commands are now I don't know anymore, I just know you have to be able to speak English in both Windows and Android
