Is there a quicker way to lock an open vault on iOS than going into: Settings | Security | Lock Now?
I somehow expected something like a 'Lock Now' button on the main panel, but have not been able to find it.
At this time, there is no 'Lock now' button on the main panel ... but you're certainly not the first one to suggest such a feature! You will notice though, in the Settings > Security pane, there is the option to 'Lock on Exit'. This will ensure that 1Password locks whenever you switch away from the app. Does this help?
It's a possible workaround, agreed. Nevertheless we hope to see such a button in a future release :-)
Thanks so much for the feedback!
