What is an advantage of using OAuth 2.

Security Mechanisms:

API Keys (Client ID/Secret):These are static, long-lived credentials. If a Client Secret is stolen, you must reset it, update the application code, and redeploy—a painful process.

OAuth 2.0 (Access Tokens):The client uses the ID/Secret to request a temporaryAccess Token(TTL of usually 15-60 minutes).

The Advantage:The API client sends thetoken(not the secret) in the header. If this token is intercepted/compromised, it will expire shortly. The attacker cannot generatenewtokens without the original Client Secret. Therefore, the underlying credentials remain safe, and you do not need to reissue them.
