Can Apps Integrate Binance Login? Access Rules and Account Binding Guide

Binance

20 October 2026

Regular individual developers or independent apps cannot directly access Binance login. Binance OAuth 2.0 login is currently only open to "close ecosystem partners".

This means if you just want to build a small tool that lets users "log in with Binance accounts", you will most likely not get access; Binance controls its login capability as part of ecosystem cooperation, not a public self-service developer feature.

First clarify: Do you need "login authorization" or "API connection"

Many developers looking for "Binance login" have different actual demands, and the corresponding access paths vary.

If you need user identity verification — after users grant authorization, your app gets an openid to confirm "this is the same Binance user", this is standard OAuth 2.0 login. The access threshold is as mentioned above: only open to ecosystem partners, requires a partnership application via email.

If you need to perform automated trades on behalf of users — for example, quantitative trading platforms or copy trading tools that require users to authorize you to create API Keys and place orders, this uses Binance's Fast API (Link and Trade). Its access threshold is a registered business entity account: you need to log into the developer center with a verified enterprise account, apply for Entity KYB and OAuth Security KYB, and you can only create a Client ID after both reviews pass. Individual developers cannot get access to this path either.

If your app runs inside the Binance App — such as a Binance Mini Program or WebApp, you can use the JS-SDK's bn.login() or bn.getUserOpenId() for login to get an openid under Binance's system, no separate OAuth login permission application is required, on the premise that your app has been admitted to the Binance ecosystem as a mini program.

To judge which category you fall into, check if your app runs independently outside Binance, or is already part of the Binance App ecosystem. Independent apps follow the OAuth or Fast API cooperation path; in-ecosystem apps use the mini program framework's dedicated login interface.

What does OAuth login for ecosystem partners look like

Assuming you pass the partnership review and get your client_id and client_secret, the workflow itself follows the standard authorization code mode.

When a user clicks "Log in with Binance Account" in your app, your app constructs a URL that redirects to https://accounts.binance.com/oauth/authorize, with parameters response_type=code, client_id, redirect_uri, scope and state. After the user completes login on Binance's side and agrees to authorization, Binance will redirect back to your redirect_uri with a temporary code attached. Your backend uses this code to call https://accounts.binance.com/oauth/token to exchange for an access_token, then uses the access_token to call Binance's API to get user information.

The scope determines what permissions you can get. Common scopes include user:openId (get user unique identifier) and create:apikey (create API Key on behalf of users). Do not apply for scopes you do not need, Binance will check if your app scenario matches the applied permissions during the cooperation review.

Mobile apps have two integration methods: apps with backend services use the authorization code mode, send the code to your own server to exchange for a token; apps without backend services use the PKCE mode, generate code_verifier and code_challenge on the client side for verification when exchanging for tokens, to prevent the authorization code from being intercepted. If your app has both web and mobile versions, Binance recommends reusing the same pair of clientId and secret, so that the openid obtained on web and mobile is the same.

Account binding: What you get and what you cannot get after user authorization

After the user completes authorization, your app gets an openid and an access_token. The openid is the unique identifier of the Binance user for your app, different apps get different openids, Binance will not directly provide users' UID or email to you.

There is a key point to clarify: OAuth login authorization is NOT equal to API trading authorization. A user agreeing to OAuth login only means you can verify their identity, not that you can place trades for them. If your app needs trading permissions, after users grant authorization via the Fast API path, your app will create an API Key for them. The permissions of this Key are selected by users during authorization (spot, futures, leverage, etc.), your app needs to store the encrypted API Key package securely, never store it in plain text.

Users' access_token has an expiration date, you need to use the refresh_token to exchange for a new one after it expires. The openid itself does not expire, but users can revoke your authorization on Binance's side. If your app relies on continuous authorization, you need to check if the token is still valid before every critical operation, instead of assuming one-time authorization works permanently.

Realistic alternatives if your application is rejected

For the vast majority of independent developers and small teams, Binance OAuth login's cooperation threshold is a practical barrier. You have several alternative options:

Use wallet connection to replace account login. If your app is a DApp, integrate Binance Web3 Wallet's window.binancew3w.ethereum for address connection and signature verification, no Binance OAuth cooperation approval is needed. Users use wallet signature to prove ownership of the address, you get an on-chain address instead of a Binance account identity. This cannot solve the problem of "confirming the user is a Binance KYC user", but it can complete the identity verification required for most DApps.

Guide users to create API Keys manually. If you only need to read users' holdings or place trades for them, you can skip Fast API, let users create their own API Key on the Binance official website and fill it into your app. This sacrifices user experience (users need to do several manual steps), but you do not need KYB or OAuth cooperation approval. You need to remind users to only tick necessary permissions, set an IP whitelist, and inform them of your API Key storage method.

If your app really needs Binance account identity and you cannot go through the cooperation path, there is no compliant way to bypass it for now. Do not try to use simulated login, web crawlers or unofficial SDKs to get Binance account information, these practices violate Binance's terms, and you will take full responsibility for the security of users' credentials.

Confirm one thing before you submit your application

Before sending an email to This email address is being protected from spambots. You need JavaScript enabled to view it., think clearly about the connection between your app and the Binance ecosystem. Binance limits OAuth login to "close ecosystem partners", the review team will judge whether your app brings substantial value to the Binance ecosystem, not just that "your app needs a login function" is enough. If you cannot clearly state the specific connection between your app and the Binance ecosystem, you will most likely not get a positive reply to your email. Clearly write down your app scenario, user scale, and the integration points with Binance's products or on-chain ecosystem first, then send the email.
