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.

Tangem RingTake the ring off to scan. You review payments on the phone; Ring has no independent screen. Choose seedless or phrase backup during setup.
