Where they differ
Wallet recovery
Foundation Passport Prime:Magic Backups needs two of three recovery parts: two are on Keycards and one is backed up through Envoy and the phone’s cloud backup. A new wallet can instead use a manual backup: any two of three physical Keycards, or recovery words.
Block Bitkey:Phone, hardware and server keys with assisted recovery. Check service and country availability.
Ledger Flex:Recovery phrase

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.
Block BitkeyTwo of three keys are needed. Recovery involves your phone, cloud storage and the service, rather than a conventional recovery phrase.
Ledger FlexiPhone connects by Bluetooth. Android connects by USB or Bluetooth. NFC does not replace USB or Bluetooth for ordinary transactions. Cryptocurrency support depends on the app.
