It is also worth to know that the wallet should be on different devices.
Create your multi-signature wallet, if you know what exactly your are doing and don't forget to keep all seed phrases and master public keys is safe places.
And it is advisable the backups can be like this:
Seed 1, MPK 2
Seed 2, MPK 3
Seed 3, MPK 1
I saw this on a post recently and I saw it to be a good backup option.
