Is there a seed phrase in the wallet?

Tangem does not use BIP39 (seed phrase) technology, believing it to be highly insecure. The presence of a key in plain sight is a potential vulnerability. Firstly, hot and "warm" wallets always have access to this key, which can be hacked. Secondly, having the key in an unsecured location at home, work or elsewhere always involves the potential risk of compromise. Instead, Tangem offers a backup on 2 or 3 identical cards. The cards hold the keys and never share them with anyone; they are protected by an access code. You therefore have 2 or 3 duplicate keys for one vault (your wallet). They are equal, so you can keep them in different places and use any of them. The most important thing is that the keys are never in public view during their life-cycle. No bug or vulnerability in the software can expose the key at the moment it is generated. It is totally safe and secure.
