Seed Phrase Backups
Casa does not recommend that users manually back up all of the seed phrases for their key set. Recall that 2 of your seed phrases are automatically backed up (the mobile key and Casa key.) We do encourage backing up 1 seed phrase to protect against extreme scenarios that might wipe out all of your hardware devices simultaneously.
- While seed phrase backups reduce the threat of accidental loss, they increase the threat of theft since the seed phrases must also be secured.
- Seed phrase backups double (or triple) the number of sensitive items that need to be stored. In a 3-of-5 system, this would mean 10 or 15 items to protect instead of 5.
- For a better understanding of the complexity involved in managing seed phrase backups we recommend reading this blog post.
