Inventory
Add your accounts, devices, phone numbers, and authenticator apps by hand — at your own pace.
For everyday digital life
Digital safety, made understandable.
TechMastery maps your accounts, devices, and recovery paths so you can see what depends on what, spot weak points, and take one practical next step — without storing passwords.

- Metadata, not passwords

What it does
A living map of what you rely on
Not a cybersecurity course. Not a password vault. TechMastery is a focused, friendly space to see your accounts, understand how they recover, and decide what to do next — every screen built to lower the stakes, not pile on red warnings.
02
Account map
Watch how accounts, devices, authentication, and recovery paths quietly depend on each other.
03
Readiness
A gentle readiness score that shows what's solid, what's unclear, and the one thing worth doing next.
04
Simulations
Play out the real fears: a lost phone, a locked email, a password manager you can't open.
In the classroom
Built for workshops, useful on its own
The app stands alone, but it shines in a room full of people. It gives talleres a shared, hands-on structure where students ask, compare, and learn from their own setup.
- 1
Start with a story
Open with a real phishing or account-takeover story.
- 2
Map together
Map one real account and one recovery dependency, side by side.
- 3
Run a simulation
Ask out loud: what breaks if a phone, laptop, or email fails?
- 4
Leave with a plan
Walk out with one concrete action to finish this week.
Our approach
Responsibility before mastery
Security usually treats people as the weak point to be fixed. We don't. A person is never just a score or a graph — the map is a tool for your own agency, nothing more.
No shame
"Unknown" is an honest place to start. We name the gaps without making you feel at fault for having them.
Calm over fear
Guidance explains the why and helps you stay in control of your accounts — instead of scaring you into acting.
People first
The best learning is face-to-face — so the tool is made to be talked through, questioned, and adapted.
Security systems put too much burden on people. Our job is to make that burden understandable, teachable, and manageable. The TechMastery approach, informed by Emmanuel Levinas
Mission & data
Built around metadata, not secrets
TechMastery exists to help you learn your own setup and feel genuinely confident managing it. To do that we work with metadata — the shape of your accounts and how they recover — and keep the secrets out of it: we'd rather not hold them, and you're better off keeping them safe yourself.
Worth mapping here
- Account names, categories, importance, and providers
- Device relations and recovery method types
- Whether 2FA, backup codes, or key files exist
Best kept with you
- Passwords and one-time recovery codes
- Full card numbers, ID documents, or private keys
- Anything you'd be uneasy seeing in a plain list
Why this, why now
A focused answer to what students told us
The first diagnosis came from a small CETYS Ensenada class survey — participatory evidence, not a claim about every student. The pattern was clear: people weren't short on tools so much as a clear picture of their own setup.
Sustainable Development Goal 4
Quality education you can practice
TechMastery turns digital literacy into an applied skill — students don't just hear about account safety, they map it, simulate it, and act on it. That's our clearest contribution to SDG 4: Quality Education.
Open source
Built in the open
TechMastery is free and open source. Read the code, suggest an idea, or fork it for your own community — nothing about how it works is hidden.
Start with one account.
The full map can grow over time. The first win is small and real: one account, one device, one recovery path, one clearer next step.
