Multi-signature is when you need to provide multiple private keys to gain access to bitcoins. For example, 2 out of 3 or 3 out of 5. This approach can be useful for various organizations and companies. For example, you can distribute keys among 5 directors, but to access funds you need 3 of the 5 keys. Or you can use scheme 2 of 3, where:
1️⃣ You control one key.
2️⃣ The second key is controlled by a centralized organization.
3️⃣ The third key is available offline.
You can also distribute keys among relatives and friends - as you wish.
