iOS QR code Restore

Trying to restore my NEM wallet on my iPhone using my QR code, it appears to accept it but then asked for a password which I don’t know.

Why is a password required, surely the QR code alone should give me access to the wallet?

Were their any specific perametors required when setting the password?

I have also tried on an android tablet, that also asked for the ‘import password’…I try my normal passwords but none work…

This QR code contains private code but it’s encrypted with password so password is required.
If you have plain text private key (66 length) you can import without password.
