How to change your Hive account master password and private keys
In Hive, you can change all your private keys by changing your master password.
For security reasons, we recommend changing your master password and private keys from time to time.However, please be sure to back them up carefully when making changes.
This is because if you lose your password, no one can recover it for you.
Also, once you have changed your master password, go ahead and download (back up) the password & key PDF file and update your Hive Keychain settings all at once!
Steps to change your Hive account master password
In Hive,changing the master password means changing the Posting, Active, Owner, and Memo keys.It is the same thing.
The following explains the procedure for changing your master password from the HIVE WALLET.
Log in to HIVE WALLET
Access the HIVE WALLET and log in.

(In the image, I am logging in by entering the password, but you can also log in with your Posting Key using Hive Keychain.)
Open the Change Password tab
You can change your master password from the Change Password tab.

Please read the precautions carefully before changing your password.

When translated, it looks like this.
・The first rule of HIVE is: do not lose your password.
・The second rule of HIVE is: do not lose your password.
・The third rule of HIVE is: we cannot recover your password.
・The fourth rule: if you remember your password, it is not secure.
・The fifth rule: only use randomly generated passwords.
・The sixth rule: do not tell anyone your password.
・The seventh rule: always back up your password.
On Hive, backing up your password is more important than anything else, and it is emphasized that it cannot be restored if lost.
Enter your current master password
To change your master password, your current master password is required.
Enter your current master password in the "CURRENT PASSWORD" field and click "CLICK TO GENERATE PASSWORD".

This will generate a new master password.
Back up the newly generated password
The newly generated password will be displayed in the "GENERATED PASSWORD(NEW)" field.
Copy this and save it in a password manager or text file.

Make sure to confirm that the password you saved in your password manager or text file is the "newly generated master password."
Be careful not to confuse it with the "current master password" you just copied and pasted.
Re-enter the new password to update
Enter the newly generated password in the "RE-ENTER GENERATED PASSWORD" field and check the checkbox below.
The following two points are written as warnings in the checkbox section.
☑ I understand that HIVE cannot recover lost passwords.
☑ I have safely stored the generated password.

Clicking the "Update Password" button will log you out, and you will not be able to return to this screen.
Please double-check that the newly generated password has been securely saved before clicking the "Update Password" button.
*At this stage, you can only obtain the new master password. The new private keys (Posting, Active, Owner, and Memo) can be checked after the master password has been changed.
If everything is correct, click the "Update Password" button.
Complete
Once you are automatically logged out of HIVE WALLET, the master password change is complete.

At this point, the master password and all four keys—Posting, Active, Owner, and Memo—have been changed. The previous password and keys can no longer be used.
To check keys other than the master password, download the PDF file from Hive.blog.
The procedure is as follows.
Conclusion
In addition to HIVE WALLET, you can also change your master password and keys via Ecency and PeakD.

Regarding whether there is a way to change only specific keys, such as "only the Posting Key" or "only the Active Key," at the very least, I could only confirm the method of renewing all keys as described above using HIVE WALLET, Ecency, and PeakD.
Once you have changed your master password, be sure to complete the following two steps.
1. Download the PDF file containing your master password and keys
2. Update your Hive Keychain settings
