Microsoft Entra ID: AADSTS65001: The user or administrator has not consented
The app asked for permissions that nobody in this tenant has agreed to grant it. Consent is per tenant, so an app that works in your own tenant fails in a customer's, and adding a new scope to an existing app needs fresh consent too. Many organisations block users from consenting themselves, so only an administrator can clear it.
Quick fix
Read the commands before running them. Anything that restarts a service, deletes data or changes permissions should be tried on a non-production system first.
# The error lists the app ID and often the scope. Check what is granted
az ad app permission list-grants --id <application-client-id> -o table
# Admin consent for your own tenant
az ad app permission admin-consent --id <application-client-id>
# For another tenant, send their admin to the consent URL
# https://login.microsoftonline.com/<their-tenant-id>/adminconsent?client_id=<application-client-id>
# Daemon apps (client credentials) always need admin consent
# for application permissions: user consent is not possible
# Only request the scopes you use: each new one triggers consent againHow to diagnose Auth errors
Identity errors are almost always configuration mismatches between two systems rather than code bugs: a redirect URI registered with a trailing slash, a client secret that was rotated on one side only, a clock that has drifted past the token skew allowance. Because the identity provider deliberately returns vague errors to avoid leaking information to attackers, the provider's own log is usually far more informative than the message your application receives.
If the quick fix above does not resolve it, work through these steps. They apply to this whole class of error, not just to this one message, which is usually what saves the time.
- Open the identity provider's log or event stream first. Auth0, Okta and Keycloak all record a detailed reason that they never send back to the client.
- Compare the redirect URI byte for byte, including scheme, port and trailing slash.
http://localhost:3000/callbackandhttp://localhost:3000/callback/are different URIs. - Decode the token rather than guessing. Paste it into a local JWT decoder and check
iss,aud,expandnbf, never a remote paste site, because tokens are credentials. - Check clock skew with
timedatectlorntpq -p. Kerberos, SAML and JWT all reject tokens outside a tight time window, and a drifting VM clock produces intermittent, unreproducible auth failures. - For passkeys and WebAuthn, verify the Relying Party ID matches the origin exactly and that the page is served over HTTPS or on
localhost. Nothing else is a secure context.
