How can I show the user the default password on his phone?

[liveCode]

I create an app and I want the user to have to enter the password with which he opens the phone when logging in.
how do I do it?
Thanks

I don't think you can, it would be a security risk. Also, not all users have a password, they might use a PIN, a pattern, face recognition, or fingerprint. Why do you need it?

That does sound odd.

On my Android phone I draw a pattern on-screen to log in.

For apps (such as my Bank) I have completely different passwords.

If I thought someone was making a LiveCode app to work out my log-in pattern
on my Android phone I would set alarm bells ringing.

I want him to have a screen that he will have to enter the password / fingerprint
To protect the app because the user is supposed to enter private things there

That does sound odd.

Richmond, I suspect (s)he is not referring to accessing the system password, but instead hooking into the mobile OS’s biometric authentication mechanism to authenticate the app’s specific password.

For example I can set a password for my bank app and have it authenticate with facial recognition. Nothing alarming there.

Not sure if that’s doable with LiveCode, perhaps someone wiser can advise?

To answer my own question, it is possible with an external - mergLA.

Edit: this appears to be iOS only; not sure what you’d do on Android…
