How to use Atrium

Guides for every Atrium app — vault, notes, calendar, lists, contacts, budgets, polls, invitations, registry and forms — plus sharing with family or a team, keeping your account safe, and billing.

Getting started

Create your account and start a trialSign up with an email address, get 14 days of everything with no card, and learn the difference between signing in and unlocking.
Your master passwordThe one key behind your vault, notes and calendar. Why it never leaves your device, how to choose a good one, and why we can't reset it.
Choosing a planPersonal, Family, Business or Enterprise. Every plan includes every app; they differ by people, storage and admin controls.

Vault

Logins, secure notes, files, time-locked access, the generator, authenticator codes, import and export, and the browser extension.

Logins, secure notes and filesWhat you can keep in the vault, how it is encrypted, and how folders, favourites, search and the trash work.
Importing and exporting your vaultBring your passwords in from another password manager, and take your Atrium vault out again as an encrypted backup or as CSV/JSON.
Time-locked accessLock a vault item so it can only be opened inside the windows you choose, enforced by our server's clock rather than a setting in the app.
Schedule typesDaily, weekly, monthly, date-range and cron windows, with examples of when to use each.
The password generatorCreate strong random passwords when you add or edit a login, in the web app or the browser extension.
Authenticator codes in the vaultStore a login's authenticator key alongside its password and get a live one-time code right on the item, without a separate app.
Auto-lock and the clipboardBy default, keys live only in memory and the vault locks after 15 minutes idle; you can also choose to keep a browser unlocked for longer.
The browser extensionFill in logins on the sites you visit and save new ones, with the same encryption and unlock as the web app.

Notes

Markdown notes, links and backlinks, daily notes, templates, note types, canvases, time capsules and Obsidian import.
