Stop Using '123456': The SRE Guide to Password Managers
“I’ll just use the same password for everything so I don’t forget.”
In the world of Site Reliability Engineering (SRE), this is what we call a Single Point of Failure (SPOF). If one service gets hacked, your entire business—email, banking, and client data—is compromised instantly.
At All Round Tech, we advocate for a Zero Trust approach. You shouldn’t have to remember your passwords; you should own them. Here is how to move from “vulnerable” to “hardened” using professional-grade tools.
1. Why Browser-Based Passwords Aren’t Enough
Many people rely on Google Chrome or iCloud to save passwords. While convenient, they lack the “Isolation” required for a professional Sole Trader setup.
- The “All-In” Risk: If someone gains access to your primary Google/Apple account, they have the keys to your entire kingdom.
- Limited 2FA Support: They often don’t integrate well with hardware security keys (like YubiKeys).
The SRE Solution: Vaultwarden (Self-Hosted Bitwarden)
I personally use and recommend Vaultwarden. It’s an open-source, lightweight implementation of Bitwarden that we can host on a secure, private server. It gives you 100% ownership of your encrypted database.
2. 2FA: Your “Double-Lock” Strategy
A password, no matter how complex, is only one factor. To achieve 99.99% Account Security, you need Two-Factor Authentication (2FA).

| 2FA Method | Security Level | SRE Recommendation |
|---|---|---|
| SMS/Text Message | ⚠️ Low (SIM Swapping) | Avoid if possible. |
| Authenticator Apps | ✅ Medium (TOTP) | Great for daily use (e.g., Raivo, Aegis). |
| Hardware Keys | 🔥 High (U2F/FIDO2) | The Gold Standard. Physical keys like YubiKey. |
As a licensed security professional, I recommend hardware keys for your most critical “Infrastructure” accounts: your primary email, your domain registrar, and your password vault itself.
3. How to Start Your Security Migration
Don’t try to change everything in one day. Apply the SRE Iterative Approach:
- Setup Your Vault: Install Bitwarden/Vaultwarden and create one “Master Password” that is a long, memorable sentence (Passphrase).
- Audit Your Top 5: Change passwords for your Email, Bank, MyGov, ABN/ASIC portal, and Web Hosting. Use the Random Generator (20+ characters).
- Enforce 2FA: Turn on App-based or Hardware-based 2FA for these five accounts immediately.
4. Engineering Peace of Mind
At All Round Tech, we don’t just give you a list of tips. We can help you deploy your own private password server (Vaultwarden) using Docker, ensuring your sensitive business credentials never live on a public company’s cloud.
We bring the same Data Sovereignty and Redundancy protocols used by tech giants to your home office in Wollongong.
Conclusion: Complexity is the Enemy of Security
If your security system is too hard to use, you won’t use it. A password manager makes high security easier than low security. You only remember one password; the system handles the rest.
Don’t wait for a “System Failure” to realise your defence was weak.
