The seed phrase is the Achilles’ heel of many wallets: it can be photographed, lost or stolen. Tangem takes another route — copying the encrypted private key across several cards.
How the backup is created
- The first card generates the key inside the chip.
- Backup cards are linked with end-to-end encryption.
- The key never appears on the phone or on paper.
Best practices
Keep each card in a different place: one with you, one at home and one with someone you trust or in a safe-deposit box. Always enable the access code.
