Everyday Cybersecurity
Learn to outsmart hackers, spot digital traps, and bulletproof your accounts. Build practical digital self-defense habits that keep your personal data safe in the wild.
Like Duolingo, but for Everyday Cybersecurity. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Locking the Front Door and Defending in the Wild. It starts from scratch.

Key ideas in Everyday Cybersecurity
- Phishing attacks frequently simulate crises or false deadlines to create panic
- Promises of sudden rewards or prizes lure victims into acting rashly before inspecting details
- Routine operational or informational messages rarely require panic-driven immediate action
- Anyone can set an arbitrary display name to pretend to be an executive, IT, or a reputable brand
- The domain after the '@' symbol shows the actual mail server that dispatched the email
- Logos and polite greetings are trivial for attackers to copy and paste
- The true root domain sits right before the first single slash and top-level suffix, not in subdomains added to the left
- Attackers swap visually similar characters (like an uppercase 'I' or the numeral '1' for a lowercase 'l') to spoof authentic brands
- Hyphenated keywords like 'bank-verify' do not make an attacker's domain an authentic banking site
- Hovering a mouse on desktop or long-pressing a link on mobile reveals the true destination URL in a preview box
- Hyperlinked display text can show a safe-looking address while secretly pointing your browser to a malicious site
- Inspecting the preview before tapping prevents your browser from opening untrusted sites
- Legitimate banks and services do not send unsolicited links demanding immediate password or PIN verification
- Navigating independently to an official website or using a known customer service phone number bypasses fake links
- A lock icon in a browser only proves the connection is encrypted, not that the site owner is trustworthy
- Automated cracking software tests combinations exponentially faster against short passwords, even if they use symbols and numbers
