Multisig wallet: (vocabulary)

""A multisig wallet is a wallet shared by two or more users called copayers. Depending on the kind of wallet, the number of signatures required to sign a transaction will be lower or equal to the number of copayers of the wallet. For example, a 3-3 wallet is a multisig wallet that is shared by three people and requires three signatures to sign a transaction. A 2-3 wallet is a multisig wallet that is shared by three people and requires two signatures to sign a transaction. You may also see “2 of 3” to indicate the number of copayers needed.""

Comment: keep in mind, it is hard enough for one person to keep track of crypto wallet passphrase, if the signature holders forget or sadly pass away, this can really be a problem.
