# Seed-phrase accounts

A seed phrase controls a group of deterministic EVM addresses. WalletChan
encrypts the phrase locally and tracks which accounts belong to the same seed
group.

## Generate or import

You can:

* Generate a new recovery phrase, reveal it deliberately, and confirm that you
  saved it.
* Import an existing phrase after validation.
* Preview standard derived addresses before storing the account.
* Select one or more addresses to add.
* Give the seed group and first account useful labels.

The first standard address is derivation `#0`. Later accounts retain their
derivation index and seed-group relationship.

## Add another derived account

Open **Add account → Seed phrase** and choose an existing authorized seed group
or import another phrase. WalletChan prevents accidental address collisions and
does not duplicate an account that already exists.

## Sign

Seed accounts use the same local signing capabilities as
[private-key accounts](/accounts/private-key), but WalletChan derives the
selected key from the seed phrase only within the authorized operation.

## Reveal and back up

Revealing the seed phrase requires current master authorization. An agent
password is never enough. Anyone with the phrase can control every derived
account, including addresses you have not added to WalletChan yet.

## Remove

Removing one derived account does not change the blockchain or other addresses
from the phrase. Removing the final account tied to a seed group can also make
the local phrase record eligible for removal. Confirm the exact warning and
keep an offline backup.
