Authentication

Authentication protects your health data: welcome, device pairing, PIN, trusted devices, and recovery. Security should feel calm — not like a quiz you fear failing.

💬 Buddy Tip

Store recovery information where only you can find it. A trusted device plus a remembered PIN covers most days.

🎯 Today's Mission

Confirm you know how you sign in on this device and where your recovery path lives — update it if fuzzy.

WHY?

Why this matters

Food, weight, and training data are personal. Sessions, device trust, and PIN exist so casual access stays hard while daily use stays smooth.

Most auth pain is forgotten PINs, new phones, or skipped recovery setup. Fix those once; logging stays uninterrupted.

Invitation-only beta means access is intentional. Follow onboarding prompts rather than inventing workarounds that weaken trust.

WHAT?

What to understand

Auth building blocks.

  1. 1

    Welcome / onboarding entry

  2. 2

    Device pairing for your account access

  3. 3

    PIN for quick local protection

  4. 4

    Trusted devices for smoother return visits

  5. 5

    Recovery paths when a device is lost

Myth
Skipping recovery setup saves time.

Truth: It costs a crisis later. Set recovery while calm.

Myth
Sharing my PIN with a partner is fine if we share goals.

Truth: Prefer separate access patterns. Shared PINs blur responsibility and safety.

HOW?

How to do this in real life

Treat auth like brushing teeth — brief, regular, non-dramatic.

  1. 1

    Complete onboarding prompts without rushing past recovery

  2. 2

    Set a PIN you can recall under travel stress

  3. 3

    Mark this phone as trusted if offered and it’s yours alone

  4. 4

    When you get a new device, pair deliberately; revoke the old one if needed

  5. 5

    If locked out, use official recovery — avoid unofficial “reset” folklore

  6. 6

    Email hello@kcal.lol only after you’ve tried the in-app recovery path

How Buddy helps

Auth keeps Buddy’s diary yours. The product assumes privacy is part of coaching trust — not an afterthought.

New phone checklist

Install → sign in / pair → confirm PIN → verify a recent Foodiary day syncs → revoke trust on the old device if it’s leaving your control.

  1. 1

    Do not factory-reset the old phone until the new one shows your data

  2. 2

    Keep recovery material handy during the switch

Shared households

Use Spaces for collaboration. Don’t turn one login into a household account — ground truth gets muddy and security weakens.

❤️ Encouragement

Secure enough to protect you, simple enough that you still open Home tomorrow — that’s the auth goal. Set it once, then go log lunch.
