Protect Your Digital Life

Secure the accounts, devices, data, and recovery paths that matter most before a crisis happens.

What you’ll leave with

A hardened email account, password manager, stronger sign-in, tested backups, and an incident recovery card.

Course handbook

Know the route before you begin.

This is the working brief for the full course: who it serves, what to prepare, what good work looks like, and the language you will use along the way.

Who this is for

For an ordinary person who wants a realistic security baseline across email, finance, social, cloud, and devices. This is defensive hygiene—not hacking—and it prioritizes account recovery, unique credentials, phishing resistance, updates, backups, and a calm incident plan.

Prepare before lesson one
  • Choose a reputable password manager and update your primary devices.
  • Gather recovery emails, phone access, device lists, and current backup information.
  • Reserve uninterrupted time for email, financial, and identity-provider accounts first.
  • If you suspect active compromise, use a clean device and the provider's official recovery path.
Your final project

Finish with proof you can use.

A personal security file with a critical-account map, unique managed passwords, phishing-resistant or strongest available MFA, secured devices and recovery methods, a tested 3-2-1-style backup plan, and a printed incident checklist.

Three operating principles

The rules behind the steps.

01

Email is the recovery root

Control of primary email often enables password resets elsewhere, so it deserves the strongest protection first.

02

Unique credentials contain damage

One stolen password should not unlock every account; reuse turns a single breach into a chain reaction.

03

Recovery is part of security

Updates and MFA prevent many incidents, while tested backups and documented recovery reduce the impact of those that still occur.

Working vocabulary

Key terms worth knowing.

MFA
Authentication requiring more than one factor, ideally something resistant to phishing such as a security key or passkey.
Passkey
A cryptographic sign-in credential tied to a device or password manager and designed to resist phishing.
Phishing
A deceptive message or site intended to steal credentials, money, or sensitive information or trigger unsafe action.
Recovery code
A one-time backup code used when a normal authentication method is unavailable.
3-2-1 backup
A resilience pattern using three data copies, two storage types, and one copy separated from the primary environment.
Your route

Six lessons.
One finished outcome.

Work in order the first time. Each lesson makes something the next lesson can use.

  1. 1
    Up next

    Map your critical accounts

    Identify the accounts and recovery channels whose loss would cause the most damage.

    Move to unique passwords

    Stop one breached password from unlocking multiple accounts.

  3. 3
    23 min

    Turn on stronger sign-in

    Add a second barrier and secure the fallback paths around it.

  4. 4
    24 min

    Spot and stop phishing

    Break the urgency-and-impulse pattern used to steal credentials or money.

  5. 5
    27 min

    Secure devices and backups

    Reduce damage from loss, theft, malware, hardware failure, and accidental deletion.

  6. 6
    21 min

    Prepare for an incident

    Make the first hour of an account takeover or lost device calmer and faster.
