How To Change Telos (or eosio) Keys Using Anchor
Updating your Active and Owner keys on Anchor
Important Notes:
- Save every version of your keys (from Genesis keys to every time you update your keys)
- You may need to refer back to older versions of your keys for possible future chains.
UPDATING PERMISSIONS
You will want to change both the Active and Owner Permissions on your account. Change one at a time.
- Download Anchor for Desktop (which has the necessary features not supported in the Anchor Mobile App) from https://greymass.com/en/anchor/download
- Click “Tools” in the Menu
- Under the ‘Securities’ section, click “Manage Keys”
- Click “Generate Key Pairs”
- Once you see your two sets of new keys, Click “Copy to clipboard”
- Save this key in a secure location.
- Write it down offline. Make sure you have the Private Key for the corresponding Public Key written down.
- The public key always starts with EOS and then the Private Key is right below it.
- Never show your Private Key to anyone
- There are many ways you can save your keys, such as:
- “Save Keys to Wallet” will save the keys inside Anchor. This is recommended for everyone. Remember to backup your Anchor
wallet if this is the only place you choose to save your keys. - “Copy to clipboard” allows you to copy and paste the private keys elsewhere on your computer, for example in a text file.
- Click on the “eye” which displays your private keys on your screen (careful!) and allows you to write down your private key on a piece of paper. Make sure to double and triple check that your correctly transcribed your key and then store it in a safe location. Anyone who finds this private key controls the account and all the assets in it.

- Click “Import Accounts”
- You can either manually import your account or allow the server to automatically detect it
- Use your newly generated Owner Key
- Paste your new Private Key
- Click “Import Account”
Congratulations! You have successfully generated a new key pair and can now control your Telos account through your Anchor wallet!
