01What
Adds a second key pair (a 'regular key') that can sign transactions for your account, so your master key — the one your seed generates — can stay offline.
02Why you'd use it
If a key you use daily leaks, you want it to be a replaceable one. With a regular key set, you can rotate keys after a scare without moving the account.
03How
- 1Generate a brand-new wallet (its address becomes the regular key — you keep its seed too).
- 2Enter that new wallet's address in Regular Key Address.
- 3Submit with your current key and confirm tesSUCCESS.
- 4From now on, sign daily transactions with the regular key's seed. Store the master seed somewhere safe and offline.
- 5To remove the regular key later, submit this tool with the field left empty.
Watch out
- Setting a regular key does not disable the master key — that requires the asfDisableMaster flag in Account Settings, done separately and carefully.
- The regular key is a full signing key: whoever holds its seed controls the account. Guard it like money.
- Never set the regular key to an address you do not hold the seed for — you would be handing signing power to someone else.
For example
A small business keeps its master seed in a safe. Day-to-day payments are signed with a regular key on the office laptop. When the laptop is stolen, they use the master key once — to replace the regular key — and nothing is lost.
