How can i get my old passcode?

Hi there Osvaldogg17,

A forgotten device passcode cannot be recovered. To be able to access the device again, you will need to reset your device.

If your device is running an iOS version earlier than 15.2, the steps in this article would help reset your device and you could then set a new passcode: If you forgot your iPhone passcode - Apple Support

If you have an iPhone and it's running iOS 15.2 or later (same with an iPad device running iPadOS 15.2 or later), then the steps below will help resolve this for you:

"How to reset your device

If you're using an eSIM, contact your carrier before trying these steps and ask for a QR code to set up your eSIM again.

1. From your device's Lock Screen, try to enter your passcode five times until the "[Device] Unavailable" screen appears and your device asks you to try again later.
2. When you're able to, continue to enter your passcode until the "Security Lockout" screen appears and you get the Erase [Device] option in the bottom corner of the screen.
3. 
4. 
   
5. Tap Erase [Device], then tap Erase [Device] again to confirm.
6. Enter your Apple ID password to sign out of your Apple ID on your device.
7. Tap Erase [Device] to permanently delete all of your data and settings.
8. When your device restarts, follow the onscreen instructions to set up your device again, restore your data and settings from a backup, and set a new passcode.

If you can't follow these steps, you can use a computer to reset your device."

Those steps, and more information, can be found here: If you see an iPhone or iPad unavailable message or Security Lockout screen - Apple Support
