My iPad is asking again for a passcode after 10 days from reset

You need to remember the passcode you set as it will still be required to enter at times such as:

• The device has just been turned on or restarted.
• The device hasn’t been unlocked for more than 48 hours.
• The passcode hasn’t been used to unlock the device in the last six and a half days and Face ID hasn't unlocked the device in the last 4 hours.
• The device has received a remote lock command.
• After five unsuccessful attempts to match a face.
• After initiating power off / Emergency SOS by pressing and holding either volume button and the side button simultaneously for 2 seconds.

This is outlined at About Face ID advanced technology - Apple Support

At this point you'll need to reset your iPad again following If you forgot your iPad passcode - Apple Support

FaceID (or TouchID) is not a replacement for your Passcode. The biometric authenticator provides an alternative method of accessing your device or protected credentials.

Much of your iPad’s advanced functionality simply won’t work unless a Passcode has been set. As documented by Apple in its Security Guide, for devices with TouchID or FaceID enabled, you device Passcode is reportedly required in the following circumstances…

A passcode or password is also required if the device is in any of the following states:

• The device has just been turned on or restarted

• The user has logged out of their Mac account (or hasn’t yet logged in).

• The user hasn’t unlocked their device for more than 48 hours.

• The user hasn’t used their passcode or password to unlock their device for 156 hours (six and a half days), and the user hasn’t used a biometric to unlock their device in

4 hours.

• The device has received a remote lock command

• The user exited power off / Emergency SOS by pressing and holding either volume button and the Sleep/Wake button simultaneously for 2 seconds and then pressing Cancel.

• There were five unsuccessful biometric match attempts (though for usability, the device might offer entering a passcode or password instead of using biometrics after a smaller number of failures).

When Face ID with a mask is enabled on an iPhone, it’s available for the next 6.5 hours after one of the following user actions:

• Successful Face ID match attempt (with or without a mask)

• Device passcode validation

• Device unlock with Apple Watch

Any of these actions extends the period by an additional 6.5 hours when performed.

A forgotten or unknown iPhone/iPad passcode cannot be recovered - and neither can it be reset or modified from another device. If you see a waiting period you can wait and try again to input the correct Passcode; otherwise, the iPad must be restored.

Passcode Reset gives you 72 hours to use your old Passcode to access your device; when you access your device in this way, you must change your passcode again immediately:
