With version 1.5 we introduced new functionality that offers you to check your wallet password/pin for peace of mind.
If you use version prior to v1.5.9 you have to enable "Advanced Mode" under "Settings" -> "Preferences".
Then go to a wallet, click on "MORE" and select "Verify Wallet" function:
You will be asked for the password by the application and pin on the device. After input you will get a success or a failure report.
