You can easily set-up a 2 of 3 seed phrase backup using seedxor

Provides similar benefits to geographically distributed multisig wallets, but for seed phrase backups

• any 1 of 3 sites can be compromised with master seed phrase remaining secure

• any 1 of 3 sites can be destroyed & master seed phrase can be restored

Provides significant increase in seed phrase security & redundancy

Steps:

1. create master seed phrase using seedxor with 3 source seed phrases

2. make 2 copies of each of the 3 source seed phrases

2. distribute copies of source seed phrases (A, B & C) across 3 locations as follows:

• Location 1: A, B

• Location 2: B, C

• Location 3: C, A

4. access any 2 sites to reconstruct master seed phrase using seedxor

5. for added security, add a passphrase to the master seed phrase

I am not sure why this is not more widely talked about? Am I missing something?

Seedxor can be set up suing the following tools:

• for free using paper (https://github.com/Coldcard/wordlist-paper/blob/master/worksheet.pdf)

• for free using an html tool like this (https://github.com/BitcoinQnA/seedtool) - **only use off-line & air gaped!**

• using a coldcard (https://seedxor.com/)
