After creating a wallet using Secret Numbers, there is an option to secure the wallet with a passcode or passphrase. this is used to verify every time coins are sent, there will be a passcode / passphrase to authorize the spending of the wallet.
Because this is only an authorize password for the App when sending coins, I suggests to rename it to password instead of passphrase where it is confusing with the Mnemonic Passphrase that most people are used to.
I have a few clients who tried to use the XUMM-App for the first time and got this passphrase confused and end up very worried about their coins being exposed to surveillance cameras viewing them every time they use their wallet.
I have spent time to review the code and assured them that the passphrase use in that situation is really a wallet password. Hence I suggests the App changes the wording to correct this confusion.
Thank you
