Like Duolingo, but for Everyday Cybersecurity. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

Key ideas in Everyday Cybersecurity
- Treating any account as 'unimportant' fails if its password matches your important accounts
- Attackers use automated tools to try breached email-and-password pairs across hundreds of popular services
- A breach on an obscure, insecure website directly compromises every other account sharing that exact credential
- A password manager creates and autofills long, randomized credentials for every account
- The user only ever needs to remember a single, strong master passphrase to unlock their vault
- Unique credentials prevent a compromise on one site from spreading to any other account
- MFA requires a second proof of identity that the attacker does not have, such as a physical device or biometrics
- A stolen password alone is insufficient to complete the sign-in process when MFA is enforced
- The second factor operates independently from the password factor
- SMS verification relies on cellular networks where attackers can redirect numbers via SIM swapping
- Authenticator apps run locally on your phone without relying on text messages
- Physical keys require actual hands-on contact with a physical token to approve a sign-in
- Passkeys use cryptographic keys tied directly to the genuine web address, refusing to authenticate on a fake domain
- There is no shared secret or typed password for the fake site to capture or record
- Your private authentication key stays locked inside your device's secure hardware
- Phishing attacks manufacture tight deadlines so fear rushes you into clicking before you check if the message is real
