A family password vault · Lập trình với Martin

A vault is the home password hub

A family password vault is one app or service where a parent (with you) saves passwords for school, games, email. You know the vault lock — the main password or the way you get to it with a parent. The vault remembers long sentences. You remember less.

Without a vault people write passwords on scraps, into notes called “passwords”, into chat “so we do not forget”. All wrong. A vault is not a sticker on the monitor.

Examples (a parent picks): Bitwarden, 1Mật khẩu, iCloud Keychain, Google Mật khẩu Manager with a family account, school Workspace — what you use at home.

⚠️

You do not send the main vault password. It is not a password for a game. It is the key to the list of keys. A parent and you know it — at the table, not in Discord.

What belongs in the vault

a school account (a sentence from a parent)
game accounts
Wi‑Fi at home — if a parent wants
2FA backup codes
a PIN from parent banking no — that is only a parent

You do not write friends’ passwords into the vault. Only yours and family ones a parent approves.

💡

When school changes the password for you, a parent updates it in the vault after the change. They delete the old password in the vault. One truth.

What does not belong in the vault

a photo of a scrap in the gallery
a shared document “family passwords” in class
a message “the password is …” to yourself in WhatsApp
the same password copied into five notes

The audit from Chuẩn bị: did you find a note called “passwords”? Today you move it into the vault or delete it — with a parent.

How to set up a vault — with a parent

A parent picks the service. The main vault password = a long sentence at the table. First record: school. Second: a game. Different sentences. Delete scraps called “passwords”. You tell a friend: passwords are in the vault, not in chat.

How it fits the projects

🏠 Family rules. Mật khẩus in the vault, not on paper on the desk.

📱 Mật khẩu audit — the next lesson. Phone audit — a note called “passwords” gone.

Now you 💪

With a parent, set up a vault or open an existing one. Add two records: school + one game. Delete one old note with a password, if it exists.

The vault works. Two records inside.
No password in chat, a notebook, a photo of a scrap.
Into the rules: The vault = the only place for passwords at home.

✅

Check: The vault exists. Trường and a game separately. Paper “passwords” gone. The main vault password not in chat.

What to take from this lesson

A vault = one lock, many passwords.
A parent + you. Not the whole class.
An update after a password change.
A note called “passwords” in the phone gone.
