BASIC AUTH GENERATOR
Create properly formatted HTTP Basic Authentication headers by encoding your credentials in Base64. Perfect for API testing, debugging REST endpoints, and integrating with services that require Basic Auth. All processing happens in your browser for complete privacy.
HTTP Basic Authentication is a widely-used authentication protocol built directly into the HTTP standard. This tool generates properly formatted Authorization headers by combining your username and password with a colon separator, then encoding the credentials using Base64. While simple to implement, Basic Auth should always be used over HTTPS connections to protect credentials from interception, as Base64 encoding is easily reversible and provides no encryption on its own.
Perfect for API testing, debugging web services, creating cURL commands, and integrating with legacy systems that require Basic Auth. Instantly generates ready-to-use Authorization headers, Base64-encoded credentials, and practical code examples for JavaScript fetch and cURL. All processing happens locally in your browser - no data is sent to any server.
