When creating accounts XUMM offers two security levels: bio-metric (suitable for holding smaller amounts intended to be used more frequently) and passphrase (higher security but somewhat harder to use).

This article is for accounts set to use passphrases only and does not apply to accounts using bio-metric security.

The procedure below allows users to recreate the account which provides an opportunity to input a new passphrase.

========= Before Starting =========

Have a copy of the secret numbers ready to use.

Good idea to have a pen and paper.

This will take 15-20 minutes minimum and will require full concentration.

===================================

Delete the Account in XUMM

  1. Click the gear icon at the bottom-right of the home screen to open the Settings screen
  2. Select Accounts
  3. Select the 'Edit' option on the account to be deleted
  4. Select 'Delete this account' (in red at the bottom of the screen)
  5. Select 'Yes, I'm Sure' on the warning screen

Recreate the Account in XUMM

  1. Click the gear icon at the bottom-right of the home screen to open the Settings screen
  2. Select Accounts
  3. Select the '+' symbol (top-right)
  4. Select 'Import existing account'
  5. The next screen defaults to the correct choice - 'Full Access' - so just hit Next
  6. The next screen defaults to the correct choice - 'Secret Numbers' - so just hit Next
  7. Input the secret numbers from the original account using the '+/-' buttons to change the number and the '>' to move to the next number. This is quite some some work but for good reasons.
  8. The next screen asks about security level. The choices are 'bio-metric' (face scan/fingerprint) or passphrase (which is more secure).
  9. Choose 'Passphrase'
  10. Input a passphrase (N.B. a PHRASE - not a passWORD) long enough to be difficult to guess.
    Good idea to work it out on paper first.
    *** If upper-case letters or non-alphanumeric symbols (like [email protected]#$) are used to make the passphrase then they will have to be input EXACTLY the same way when doing a transaction. The same goes for any space characters ***
  11. Confirm the passphrase and hit next
  12. Copy the public address if you want in the next screen
  13. Provide a label for the account

Store the secret numbers and the passphrase securely offline.

Offline or 'cold' storage is outside the scope of this article. There are several methods each having pros and cons.

Anyone who has access to the credentials (secret numbers, passphrase) has control of the digital assets in that account. There is no way to recover digital assets lost in this manner.
