Protect the accounts that unlock other accounts

Begin with your main email account and the services that hold important personal or work information. Review their security settings using the service's own app or a known address. The UK's National Cyber Security Centre recommends two-step verification for important accounts where it is available.

List how you would recover access if you lost a device. Check recovery details and follow the provider's instructions for storing recovery codes. Keep that information somewhere appropriate for its sensitivity rather than leaving it in an unprotected project folder.

Use separate credentials and supported sign-in protection

Avoid reusing a password across important services. A reputable password manager can help maintain separate credentials, but it also needs a secure setup and a recovery plan. Read its official guidance before moving a large set of accounts.

When an account offers additional sign-in protection, review the available methods and follow the provider's current instructions. Do not approve an unexpected sign-in request just to make it disappear. Investigate it through the account's known security page.

Keep software and permissions under review

Use supported update mechanisms for your operating system, browser and important applications. Check that updates are actually completing, especially on a device that is rarely restarted. If a device is no longer supported, plan how to replace or isolate its role.

Review applications and browser extensions you no longer use. Remove unnecessary access through the normal account controls, and read permission prompts before accepting them. A familiar logo or a polished page does not establish that a request is legitimate.

Slow down when a request creates pressure

Treat urgency as a reason to verify a request through another known channel. If a message asks you to disclose a code, make a payment or change account access, confirm its origin independently. Do not use the suspicious message's contact details as your only verification route.

This checklist reduces common avoidable risks but does not guarantee security or diagnose a compromised device. If you believe an account is already affected, use that provider's official recovery process and seek appropriate help. Keep backups of important data and test that you can restore them.

Questions & answers

Where should I start if I have many accounts?

Start with email and other accounts whose loss would cause the most harm, then work through the rest using a written checklist.

Should I share a sign-in code with someone claiming to be support?

Use the service's official support and recovery instructions. Do not disclose codes in response to an unverified request.

Does this checklist guarantee safety?

No. It is a basic review process, not a guarantee or a substitute for incident-specific help.
