⚡That is an elite air-gapped setup! You're 90% of the way to the best security possible. The only natural next step is a 2-of-3 Multisig vault.

Setup: Use all three (SeedSigner, Coldcard, Passport) to generate three separate keys. Use a coordinator wallet like Sparrow Wallet (or Specter) to combine them into a 2-of-3 scheme.

The Win: If you lose one device or one key is compromised, your funds are still safe. No single point of failure! It's worth the slightly complex setup. 🛡️

thanks for the advice

i will consider it

i only dont like to change my seed to often

But consider you have to backup 3 pieces of information (+ the descriptor wallet information), preferably in different locations, cause having it all at home doesn't makes sense. This would make accessing it a lot harder, but not just for an attacker, also for yourself.
