Everything I say about non-obscuring, and notes that you probably don't need it at all; devices are personal and those with secure info better lock the device -- device lock hints: make gestures clear, pattern codes, etc. ALSO, some notes about best practices for pattern and numeric unlock; it is easy to crack a lock by fingerprinty screens, so if truly high security, make it random position -- variation maybe cut by not design but security requirements, and designs that fall from that... Low: None, Mid: Pin/Pattern, High:??? + randomizing and non-form systems so the handset has no way of thwarting you and saving the entry |
