Before you choose

Consider

Foundation Passport PrimeInitial setup uses Envoy and Bluetooth. To restore existing words without Magic Backups, ask Foundation support to confirm the steps for your KeyOS version before setup. Ethereum and Solana need the separate Legacy Mode beta on a computer.

Trezor Safe 3USB signing on computer or Android; the iPhone app does not let this model approve transactions.
