Antwort auf: Ich habe mein Gerät verloren – wie kann ich es sicher von einem Shamir-Backup-Satz wiederherstellen, ohne ein Model T?
The best security practice is to have a spare device that supports SLIP39 so you can conveniently recover your wallet anytime and send your funds elsewhere for peace of your mind.
Alternatively you can recover your wallet in some 3rd party interface such as Electrum (in order to send your funds elsewhere) however as long as your master secret is not generated offline (in hardware wallet) but in some hot wallet, you should not consider your funds safe.
Also, If your lost device is protected by PIN and (ideally high entropy) Passphrase, the chances of someone brute-forcing into your wallet are close to zero.
The most important is that your Recovery seed/Shamir backup is safe. If that would be compromised or lost, nobody (not even swift answer of support) could help you.
That’s the beauty and also risk of self-custody.
