How to bypass password for startup

Hi FRANCISCO GALLETTI,
Welcome to Microsoft Q&A forum. I'm happy to help.

In your case, you can boot into Advanced Boot Options, then enable Built-in Administrator account or making a new Administrator account to change your current account password.

Just try these following steps:

1. Boot into Advanced Boot Options: Restart your computer and as soon as the Windows logo appears, press and hold the power button to force a shutdown. Repeat this process twice. On the third start, Windows should enter the Automatic Repair environment
2. From there, navigate to Troubleshoot > Advanced options > Command Prompt. This will open the Command Prompt window
3. Type the following command to activate Built-in Administrator account

      net user administrator /active:yes  
   

   Please note that if your Built-in Administrator Account was renamed, you need to replace administrator on the command above to the exact username*.*
4. Reboot your computer, then Boot into Advanced Boot Options again
5. This time, navigate to Troubleshoot > Advanced options > Startup Settings > Restart
6. Once the device reboots, in the Startup Settings screen, press F4. Your computer will reboot into Safe Mode
7. Normally in Safe Mode, your computer will automatically login to Built-in Administrator account. If it doesn't, manually login to it with username Administrator / or [your-pc-name]\Administrator and empty password

While you successfully logged in as Built-in Administrator, you may change your current account password.
