Lost Secret Key, then what?
I think I lost my Secret Key to the Hiro Wallet. What should I do?
Secret Keys control the funds sent to individual Stacks addresses. Secret Keys are either a 24 word secret phrase that users were prompted to record in the process of setting up their Leather, or secret keys stored on a connected hardware wallet device. A full overview and background on Secret Keys is available here.
In the past, users were able to use either a Trezor or Ledger to set up a Leather address as an alternative to generating a new secret key for their STX holdings. As such, they may have 12, 18 or 24 word secret keys that are associated with their hardware wallets that might have been used to set up Leather originally (or a preceding wallet such as Hiro Wallet or Stacks wallet).
Users are also encouraged to check any safes / password managers or paper files with important information to find their 24-word secret keys if they have never used a hardware wallet.
