Available after Zoom approves the app listing. BKey Proof of Me is not in the Zoom App Marketplace yet. This page describes the panel as it works today.
BKey Proof of Me is a Zoom app for asking a participant in your meeting to verify. The phone of the BKey account you ask shows a request for a quick face scan in the BKey app. When the scan is completed, the panel shows Authenticated next to the name you entered. Each proof is bound to the meeting you are in. A proof made for a different meeting is rejected here, even when its signature is valid, so a proof cannot be forwarded from another call.

​
What the badge tells you

An Authenticated badge means:
  • Someone completed a live facial-biometric scan in the BKey app, on the phone registered to the BKey account you asked.
  • That phone signed a proof for this Zoom meeting. Before showing the badge, the panel checked the signature, that the proof names this meeting, and that the proof is fresh.
The badge also shows the verification level that the proof states, for example Authenticated · SILVER. If the proof states no level, the badge says tier not stated. For the most recent verification, the panel also shows a What was actually proved section: the BKey identifier that signed the proof, the meeting it is bound to, the verification level and the device-check status. What the badge does not tell you:
  • That the person on your screen is the person who scanned. The scan happens on their phone, not in the Zoom video. The badge does not compare the face in the video with the face that was scanned, and it does not analyse the video for deepfakes. Use it together with what you see and hear.
  • Their legal name or identity documents. BKey does not check an ID document for this badge. It proves control of a BKey account, not a legal identity.
  • Their Zoom display name. The name shown in the panel is not part of the proof. Only the BKey account is.
  • That it is still them later. The badge records one check at one point in time. It does not expire or change, and the panel never re-runs a check by itself. If you need a current proof, add the person again and ask them to verify.
  • That what they ask of you is legitimate. A verified person can still ask for something you should confirm through your usual channels.

​
Before you start

You need:
  • The Zoom desktop app for Windows or macOS. Zoom does not let you add apps from the Zoom mobile app.
  • Zoom Apps turned on for your Zoom account. On a company account, an admin may have to turn on Zoom Apps, or approve BKey Proof of Me, before you can add it.
You do not need the BKey app to ask someone to verify. The person you ask needs:
  • The BKey app on their iPhone, signed in, with their face set up in BKey.
  • To tell you their BKey identifier. You send the request to it. It starts with did:bkey: and is shown as ID at the bottom of the Settings screen in the BKey app. Tapping it copies it together with the app version, so they should send you only the part that starts with did:bkey:.
They do not need to add the Zoom app. BKey does not accept a request addressed by email address yet. The panel offers Use email instead, but a request sent that way ends in Couldn’t verify.

​
Add the app

  1. Sign in to the Zoom App Marketplace with your Zoom account.
  2. Search for BKey Proof of Me and open its listing.
  3. Click Add.
  4. Review the permissions Zoom shows you, and authorize the app.
If you see Request instead of Add, your Zoom account’s owner or admin has to approve the app first. Click Request to send them a request. You can also add the app from the Marketplace tab of the Zoom desktop app, or during a meeting from Apps in the meeting controls. Having trouble? See Troubleshooting.

​
Open it in a meeting

  1. Start or join a meeting in the Zoom desktop app.
  2. In the meeting controls, click Apps. If you do not see it, look under More.
  3. Click My Apps, then BKey Proof of Me. It opens in the side panel.
The panel reads the meeting’s ID from Zoom and binds your requests to it. If Zoom cannot tell the panel which meeting it is in, the panel blocks verification rather than guess.

​
Ask someone to verify

  1. In the panel, enter the participant’s name and their BKey identifier, then click Add. The name is a label for you: it stays in your panel and is not sent to BKey.
  2. On their row, click Ask to verify.
  3. Tell them in the meeting that you have just sent the request. The BKey app on their phone says that a verification partner is asking, and shows a technical ID for the requesting app, an internal ID for the meeting, and Presence only under what is shared. It does not show which participant asked, so telling them yourself is how they know the request is yours.
  4. They tap Begin verification and complete the face scan. They have under a minute to do this before the request lapses on their phone.
  5. The row shows Authenticated a few seconds after the scan.

​
What each state means

These requests all look the same in the panel: one that is declined, one that is not answered in time, and one sent to an identifier that has no BKey account. Each stays at Requested and then changes to Couldn’t verify. The panel does not tell you why a request got no answer.

​
For the person being asked

The request appears in the BKey app as coming from a verification partner, with an ID for the meeting and Presence only under what is shared. It does not say which participant sent it. Verify only when the person you are talking to has just asked you to, in this meeting. Begin verification starts a short face scan. Not now declines, and no proof is shared. Despite the Presence only label, a proof you share identifies your BKey account to the person and the app that asked: it is signed under a permanent identifier for your account, which is the same in every proof you make. It contains no image of your face and no liveness or face-match scores. It does say which kind of biometric check was used, when the scan happened, and a value that identifies your current BKey enrollment. See How your data is handled.

​
Remove the app

  1. Sign in to the Zoom App Marketplace.
  2. In the bottom-left corner, click My Library.
  3. Find BKey Proof of Me.
  4. In the Actions column, click the More icon, then click Remove.
  5. Optionally choose a reason, then click Remove to confirm.
In the Zoom desktop app, the same steps start from the Marketplace tab (under More if you do not see it). If your Marketplace shows Manage in the top-right corner instead, click Manage, then Added Apps, find BKey Proof of Me, and click Remove. If a Zoom admin added the app for your whole account, ask the admin to remove it. Zoom’s own instructions: Adding and removing Marketplace Apps for personal use.

​
What removing the app does

  • It deauthorizes the app for your Zoom account. Zoom revokes the access you granted when you added the app. BKey is not notified of the removal.
  • The panel no longer opens in your meetings, and you cannot ask anyone to verify through it.
  • Nothing changes for the people you asked. Their BKey accounts and the BKey app are not affected.
  • Verifications that were already completed are not undone or deleted. See How your data is handled.
  • You can add the app again at any time.

​
How your data is handled

The app asks Zoom for the meeting’s unique ID, to bind each proof to this meeting, and for the meeting’s topic, to show which meeting the panel is in. It does not ask Zoom for your meeting’s audio, video, chat or participant list. The name you type for each person stays in your panel and is not sent to BKey. The BKey identifier you type is sent to BKey with the request. An email address entered with Use email instead is also sent to BKey, which rejects it. The list of people and their results is kept only while the panel is open. To limit repeated requests, the app’s server holds your IP address and the identifiers you ask, in memory. The face scan runs in the BKey app on the other person’s phone. The proof your panel receives contains no image of their face and no liveness or face-match scores. It does say which kind of biometric check was used, when the scan happened, and a value that identifies their current BKey enrollment. The proof does identify the BKey account that answered. It is signed under a permanent identifier for that account, which is the same in every proof the account makes. So a proof is more than a presence signal: two proofs from the same account can be linked to each other, including proofs given to different requesters. When you ask someone to verify, BKey records the request and its result: the BKey account that was asked, the meeting the proof is bound to, the time, and the signed proof. BKey keeps the same kind of record for other approvals made in the BKey app. Removing the Zoom app does not delete the records of verifications that were already completed, because each one is an approval the other person signed on their own phone. The privacy policy explains what BKey keeps for these checks and how to exercise your data rights.

Troubleshooting

I don’t see Apps in the meeting controls. Look under More. If it is not there, Zoom Apps may be turned off for your account. Ask your Zoom admin to turn them on. The app won’t open in a meeting. The meeting host can suspend Zoom Apps for the whole meeting from Zoom’s in-meeting security controls. Ask the host whether apps are allowed in this meeting. I see Request instead of Add. Your Zoom account’s owner or admin has to approve the app. Click Request and wait for their approval. I can’t add the app on my phone. Zoom does not let you add apps from the Zoom mobile app. Add it from the Marketplace website or the Zoom desktop app. The panel says verification is blocked. The panel verifies only when Zoom tells it which meeting it is in. Close the panel and open it again from Apps inside the meeting. The badge stays on Requested. The panel waits about ten minutes for a result, and you cannot ask again until then. Check that you entered their BKey identifier, and ask them to open the BKey app: they have under a minute to answer. If the time runs out, the badge changes to Couldn’t verify, and you can click Retry. Requests to one person keep ending in Couldn’t verify. Check that you entered their BKey identifier and not an email address: BKey does not accept requests addressed by email yet. Retry sends the request to the same identifier or address again, so if that was wrong, add the person again with their BKey identifier. The panel also limits how many requests you can send, and how many one person can receive, in a ten-minute window, and BKey limits how many requests the app can send in total (60 a minute across all users of the app). When the panel’s limit is reached, Couldn’t verify appears straight away, and holding the pointer over it shows the reason. Each Retry counts as a new request. Wait ten minutes before asking that person again. A proof keeps failing its checks. If Couldn’t verify comes back after the person has completed the face scan, and Retry gives the same result, contact support and include the approximate time of the request.
