Can I use the same hardware wallets across multiple accounts on my profile?

Yes, you can customize the availability of the keys on your profile.

You can always use your two existing keys to create multiple vaults in a single Unchained account, like a personal account. Separately, you can also use the same hardware wallets across multiple accounts on your profile. For example, you may have personal, business, and IRA accounts but only want to use two hardware wallets in total.

Note: Long-time clients may have edited the BIP32 derivation path on different accounts in the past. This step is no longer necessary, as your keys are now available across all accounts on your profile.

Use the Connections feature to share a key to someone else's account.

How to change your key availability

Sign in to your Unchained account.
Click Keys on the left side of your screen and select the key name you want to change.
Under Account availability, toggle key permissions and click Confirm.
Success! You may now use that key to create a vault in the selected account.
