Your agents ask. You decide.
LumoAuth puts sign-in approvals, AI agent approvals and your two-factor codes in one app. When someone signs in to your organization, or an AI agent wants to act on your behalf, the request comes straight to your phone and nothing happens until you say yes.
APPROVE WHAT YOUR AI AGENTS DO
AI agents are starting to send emails, move money and change data for the people they work for. LumoAuth makes sure a person stays in charge of the actions that matter.
• See the exact action an agent is asking to take, such as "Wire $4,500 to vendor INV-7741"
• Know which agent is asking, its agent ID and whose behalf it is acting on
• High-impact actions are clearly marked so you can slow down before you approve
• Every request has a countdown. If you don't respond, it expires instead of going through
• Allow or deny with a single tap
SIGN IN WITHOUT A PASSWORD
• When you sign in to an organization that uses LumoAuth, a request appears on your phone
• Tap the number shown on your sign-in screen to confirm it's really you. Number matching stops people approving requests by accident
• See the organization, account, time and browser for every request
• Didn't try to sign in? Tap "Deny – this wasn't me" and the attempt is stopped
• Review past requests in your sign-in history
REQUESTS REACH YOU INSTANTLY
Sign-in and agent requests arrive as time-sensitive notifications, so you see them on your lock screen right away, even when the app is closed.
ALL YOUR ORGANIZATIONS IN ONE PLACE
Enroll each organization once by scanning its setup code. Work, side projects and client accounts all sit in one list, and every request tells you which organization it came from.
YOUR 2FA CODES, BUILT IN
LumoAuth is also a full authenticator for one-time codes.
• Add the standard six-digit codes used by most websites and apps
• Search across services and accounts
• Tap any code to copy it
• Swipe left or long-press for more options
SWITCH PHONES WITHOUT STARTING OVER
• Back up your codes and organization enrollments to your own iCloud
• Backups are encrypted on your device with AES-256-GCM, using a key derived from a PIN only you know, before anything is synced
• Turn on automatic sync to keep the backup up to date
• On a new phone, or after reinstalling the app, sign in to the same iCloud account and enter your PIN to restore everything
• Export or import an encrypted backup file whenever you need to
BUILT FOR SECURITY
• Approvals are signed with a key that stays on your phone
• Your backup PIN never leaves your device
• Requests expire automatically if they aren't answered
LumoAuth works with organizations that use LumoAuth for sign-in and AI agent access. The authenticator works with any service that supports standard one-time codes.
