About Basic Auth
Basic access authentication is a simple authentication scheme built into the HTTP protocol. It uses a Base64-encoded string containing a username and password separated by a colon. This tool helps you generate that string easily for your API requests or configuration files.
Privacy Note
Your credentials are never sent to a server; all encoding happens locally in your browser.

Perguntas Frequentes
Is Basic Auth secure?
Basic Auth transmits credentials as Base64-encoded text, which is easily decoded. It should always be used over HTTPS to encrypt the connection. For production systems, consider more secure alternatives like OAuth 2.0 or API keys.
What format does the Authorization header use?
The header format is 'Authorization: Basic <token>' where the token is the Base64 encoding of 'username:password'. The colon character separates the username from the password.
Can I use special characters in the username or password?
Yes, you can use any characters in the password. However, the username should not contain a colon (:) since that character is used as the delimiter between username and password in the encoding process.
