Hi there @1passquest
Travel Mode is designed to help protect customers' data when they, for example, cross borders and might have their devices searched. A border agent might compel you to unlock 1Password for them to examine, or deny you entry if you don't.
You can only turn Travel Mode on and off through My Profile on 1Password.com. There is no indication in any of the 1Password apps that Travel Mode is turned on, and it can't be turned off from there. It's designed to hide certain vaults, that you mark as Unsafe For Travel, with plausible deniability, because 1Password will look exactly the same on your phone, tablet, or computer, whether Travel Mode is turned on or off.
Please let me know if you have any questions, or would like any further help. :)
