@merisertse here is the [https://www.samsung.com/ca/support/mobile-devices/what-can-you-do-if-you-forgot-the-pin-pattern-or-password-of-your-galaxy-device/|official version] on what to do. The unofficial version says that you should have your phone connected to a previously used Wi-Fi network and then:
Enter a wrong lock screen password or pattern 5 times.
Wait 30 seconds and click the option “Forgotten Pattern”.
Enter a backup PIN or your ***Google account login (no go without this)***.
This should now unlock your phone.
If you do not have your Google account login you can only use the official way.
