Regenerate a Vault root token

Your Vault root token is a special token that gives you access to all Vault operations. Best practice is to enable an appropriate authentication method for Vault admins once the server is running and revoke the root token.

For emergency situations where your require a root token, you can use the operator generate-root CLI command and a one-time password (OTP) or Pretty Good Privacy (PGP) to generate a new root token.

Before you start

You need your Vault keys. If you use auto-unseal, you need your recovery keys, otherwise you need your unseal keys.
Identify current key holders. You must distribute the token nonce to your unseal/recovery key holders during root token generation.

Step 1: Create a root token nonce

Generate a token nonce for your new root token:

You need the returned OTP value to decode the new root token.

$ vault operator generate-root -init A One-Time-Password has been generated for you and is shown in the OTP field.You will need this value to decode the resulting root token, so keep it safe.Nonce         15565c79-cc9e-5e64-b986-8506e7bd1918Started       trueProgress      0/1Complete      falseOTP           5JFQaH76Ky2TIuSt4SPvO1CGkxOTP Length    26

Use the -pgp-key option to provide a path to your PGP public key or Keybase username to encrypt the new root token. You will need the returned PGP value to decode the new root token.

$ vault operator generate-root -init -pgp-key=keybase:sethvargo Nonce              e24dec5e-f1ea-2dfe-ecce-604022006976Started            trueProgress           0/5Complete           falsePGP Fingerprint    e2f8e2974623ba2a0e933a59c921994f9c27e0ff

Distribute the nonce to each of your unseal/recovery key holders.

Step 2: Establish key quorum with the token nonce

Use TTY to autocomplete the nonce

If you use a TTY, the operator generate-root command prompts for your key and automatically completes the nonce value.

Have each unseal/recovery key holder run operator generator-root with their key and the distributed nonce value:

$ echo ${UNSEAL_OR_RECOVERY_KEY} | vault operator generate-root -nonce=${NONCE_VALUE} - Root generation operation nonce: f67f4da3-4ae4-68fb-4716-91da6b609c3eUnseal Key (will be hidden):

Vault returns the new, encoded root token to the user who triggers quorum:

Step 3: Decode the new root token

Decode the new root token using OTP or PGP.

Use operator generate-root and the OTP value from nonce generation to decode the new root token:

$ vault operator generate-root \   -decode=${ENCODED_TOKEN}    \   -otp=${NONCE_OTP} hvs.XXXXXXXXXXXXXXXXXXXXXXXX

Use your PGP credentials and gpg or keybase to decrypt the new root token.

gpg:

$ echo ${ENCODED_TOKEN} | base64 --decode | gpg --decrypt hvs.XXXXXXXXXXXXXXXXXXXXXXXX

keybase:

$ echo ${ENCODED_TOKEN} | base64 --decode | keybase pgp decrypt hvs.XXXXXXXXXXXXXXXXXXXXXXXX
