Before you choose

Consider

Prokey OptimumInitial setup and firmware updates use Chrome on a computer. Recovery uses your 24 words on Prokey; a passphrase-protected wallet also needs its exact passphrase.

imKey ProSetup starts in imToken, and COS firmware updates require USB to a computer. Save the binding code for pairing with a new phone; it is separate from the recovery phrase.
