EOS.IO Technical WhitePaper v2 mentions that:<\/p>\n

The EOS.IO software provides users a way to restore control of their account when keys are stolen. An account owner can use any owner key along with approval from their designated account recovery partner to reset the owner key on their account.<\/p><\/blockquote>\n

However, the EOS community did not has an interface tool for users to achieve this feature. Now, Math Wallet releases \u3010EOS MultiSig Toolbox\u3011 that enables users to backup private key without mnemonics.<\/p>\n

This article mainly describes how to set \u201c account backup friends\u201d in Math Wallet and how to use \u3010EOS MultiSig Toolbox\u3011to restore control of account when the key is lost or stolen.<\/p>\n

In this case, we will backup the account reset permission of “lendeostoken” to accounts:<\/p>\n

selleostoken\u3001sendeostoken\u3001giveeostoken<\/p>\n

If lendeostoken lost his private key, we could use the other account “coincontract” to initiate MuliSig permission reset.<\/p>\n

Suggestion \uff1aBe sure to choose the accounts you trust, as two of the three EOS accounts could approve together to operate your account, be sure to choose the account you trust.
\nNote: If you are not familiar with the blockchain, please carefully set the MultiSig permissions. After setting, your current EOS wallet may can\u2019t transfer or modify the permissions again.<\/p>\n
