Account Security for Couples and Shared Households
Couples, families and housemates share Wi-Fi, subscriptions, bills and devices. How to share access safely without sharing personal passwords, and how to keep personal accounts private.
Households share a lot: Wi-Fi, streaming, utilities, shopping accounts, sometimes devices. Sharing is fine. The trouble comes when sharing means one password used by everyone, or one person's personal email and banking open to all. You can share what needs sharing and keep the rest private.
What to share, and how
| Shared need | Better way to share |
|---|---|
| Household bills and money | Joint accounts or authorised access through the bank |
| Streaming and subscriptions | Family plans with separate profiles |
| Household logins | A shared vault in a password manager |
| Wi-Fi | A strong router password, and a guest network for visitors. See the FTC's advice on securing home Wi-Fi |
| Devices | Separate user profiles and screen locks |
What to keep personal
- Your email, which controls your other accounts.
- Your personal banking and mobile money logins and PINs.
- Your password manager's main password.
- Your phone's screen lock.
- Work accounts.
Housemates
- Lock your devices and log out of shared computers.
- Secure your post. See mail theft.
- Keep ID documents locked away.
- Change the router admin password, not just the Wi-Fi password.
Relationships change. If you separate or someone moves out, review shared accounts, devices and recovery details. See when a partner or ex has access.
Signs of unwanted monitoring
If a partner insists on knowing all your passwords, tracks your phone without agreement, or you notice apps you did not install, that can be a sign of controlling behaviour. The FTC's guidance on stalkerware explains signs and support. If you feel unsafe, contact local support services.

Frequently asked questions
Is it a bad sign if we do not share passwords?
No. Keeping personal passwords private is good security, not secrecy. You can still share access to household accounts properly.
How should couples share banking?
Through joint accounts or authorised access offered by the bank, rather than sharing one person's login.
What about shared devices?
Use separate user profiles where possible, and lock personal devices with your own PIN.
