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.
Trezor Safe 7Wireless use means pairing the wallet with a compatible phone or computer and keeping its battery charged.
Use Google Chrome and allow USB access to Prokey Wallet. Install the device firmware there before first use. Linux may also need Prokey’s USB permissions rule. Check the payment on Prokey and hold OK to approve.
