Writing password protected NFC25 Tag

I want to implement writing of data on password-protected NFC 25 tag) ST25DV04K

In my case, I have enabled write protection on Area1 with password 1 set using the NFC tap App.

I want to use a known password to enable my Android and iOS to write the data on these tags.

Could you please point ot to the example or resources to implement this feature?

Our application is based on a ST25SDK you can find here:

Each application Android/iOS is based on ST25SDK and provides features to manage pwd and you can find resources (Source code) here:

As example and for Android , search in files for ST25DVChangeAreasPasswordActivity

and/or ST25DVChangePwdActivity ... ST25DVPresentPwdActivity (presentPassword) for guidelines.
