Infura RPC login refers to signing in to the Infura dashboard to manage projects and retrieve the API key or project ID used in RPC endpoint URLs. This guide explains the sign-in flow, where the project ID appears, how to construct an Infura RPC URL, and what to check when a login or endpoint fails.
What Infura RPC Login Actually Means
Infura is a managed RPC and API provider for blockchain networks. There is no separate 'RPC login' product. The phrase Infura rpc login usually means signing in to the Infura dashboard so you can create or open a project and copy the credentials that authenticate your RPC requests.
Those credentials are typically an API key, sometimes shown as a project ID. The key is embedded in the endpoint URL or sent as an authentication header. Without a valid key, requests to Infura endpoints are rejected or heavily rate limited.
So the practical workflow is: sign in to the dashboard, select or create a project, copy the project ID or API key, then build the RPC URL for the network you want to use.
- Infura RPC login is dashboard authentication, not a wallet login.
- The dashboard is where you manage projects and API keys.
- The project ID or API key is what your RPC URL uses to authenticate.
- Different networks have different endpoint hostnames under the same account.
How to Sign In to the Infura Dashboard
Infura accounts are managed through the MetaMask developer dashboard, since Infura and MetaMask share the same developer platform. You sign in with the same account credentials you use for that dashboard, or you can create a new account if you do not have one.
The exact sign-in options and interface can change over time, so treat the steps below as a general flow rather than a fixed click path. If a button label differs, look for the equivalent account or project menu.
Once signed in, you land in a dashboard where you can view existing projects, create new ones, and inspect API keys and endpoint URLs.
- Go to the Infura or MetaMask developer dashboard sign-in page.
- Authenticate with your existing account or register a new one.
- Open the dashboard and locate your list of projects.
- Select the project whose RPC endpoint you want to use.
Finding Your Project ID and API Key
After you open a project, the dashboard shows the project's API key or project ID. This value is the credential you place in the RPC URL. It is not your account password, and it should be treated as a secret because anyone who has it can consume your request quota.
Some dashboard views show a full endpoint URL that already includes the key. Others show the key separately and expect you to assemble the URL yourself. Either way, the key is the part that changes between projects.
If you manage multiple applications, create a separate project for each one so you can rotate or revoke keys independently.
- The project ID or API key is the authentication credential.
- It appears on the project detail page in the dashboard.
- Treat it like a password and avoid committing it to public repositories.
- Use separate projects for separate apps to isolate access.
Building the Infura RPC URL
Infura RPC URLs follow a consistent pattern: a network-specific hostname followed by your project ID. For Ethereum mainnet, the hostname is mainnet.infura.io and the path is your project ID.
Other networks use different hostnames, such as sepolia.infura.io for the Sepolia testnet or polygon-mainnet.infura.io for Polygon. The exact list of supported networks and hostnames is maintained by Infura and can change, so confirm the current hostname in your dashboard.
Below are plain-text examples. Replace YOUR_PROJECT_ID with the value from your dashboard.
- Ethereum mainnet uses mainnet.infura.io.
- Testnets use their own hostnames, such as sepolia.infura.io.
- Other chains use chain-specific hostnames.
- Always verify the current hostname in the dashboard.
https://mainnet.infura.io/v3/YOUR_PROJECT_ID
https://sepolia.infura.io/v3/YOUR_PROJECT_ID
https://polygon-mainnet.infura.io/v3/YOUR_PROJECT_IDUsing the Endpoint in Wallets and dApps
Once you have the URL, paste it into the RPC endpoint field of your wallet, development framework, or application configuration. Many tools also accept the project ID separately and construct the URL for you.
For JSON-RPC calls, you can send requests directly to the endpoint. The example below shows a minimal eth_blockNumber call using curl. It is plain text, not a clickable link.
If you are using a library such as ethers or web3, pass the full URL as the provider endpoint. Keep the key in an environment variable rather than hard-coding it in source files.
- Paste the full URL into the RPC endpoint field.
- Some tools ask only for the project ID.
- Store keys in environment variables or a secrets manager.
- Rotate keys if they are exposed.
curl https://mainnet.infura.io/v3/YOUR_PROJECT_ID \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Common Login and Endpoint Problems
Most Infura RPC login issues fall into two categories: account access problems and endpoint authentication problems. Account access problems include forgotten passwords, expired sessions, or signing in with the wrong provider. Endpoint problems usually mean the project ID is missing, wrong, or restricted.
If your requests return authentication errors, confirm that the project ID in the URL matches the project you opened in the dashboard. If you recently rotated a key, update every application that uses the old one.
If you cannot sign in at all, use the account recovery flow on the dashboard. If the dashboard itself is unavailable, check the provider's status page before assuming your credentials are wrong.
- 401 or 403 errors usually mean a missing or invalid project ID.
- 429 errors usually mean you hit a rate limit for your plan.
- Wrong network hostname can cause connection failures.
- Rotated keys must be updated everywhere they are used.
Infura RPC Pricing and Plan Considerations
Infura offers a free tier and paid plans, but the specific quotas, request limits, and prices change over time. Rather than relying on a fixed number, check the current pricing page in your dashboard after signing in.
For most developers, the free tier is enough to test an integration. Production applications with high traffic usually need a paid plan or a dedicated endpoint. Compare the daily request allowance, throughput limits, and archive data access against your expected usage.
If you need multi-chain RPC with a single account and predictable billing, some providers bundle several networks together. OnFinality is one option in that category, but the right choice depends on which chains you need and how you prefer to manage keys.
- Free tier is suitable for testing and low-volume use.
- Paid plans add higher limits and dedicated options.
- Check current pricing in the dashboard, not third-party summaries.
- Match the plan to your request volume and archive needs.
Infura IPFS and Other APIs
Infura also provides IPFS and other API services alongside its RPC endpoints. These use separate credentials or endpoints in some cases, so an RPC project ID may not automatically work for every product.
If you are using Infura IPFS, check the dashboard for the specific IPFS endpoint and authentication details. The same login gives you access, but the configuration is separate from the JSON-RPC URL.
For developers who only need RPC, the IPFS features are optional and can be ignored.
- IPFS uses its own endpoint configuration.
- RPC project IDs may not apply to every product.
- The dashboard lists the services enabled for your project.
- Only enable the services you actually use.
