Two OAuth2 Flows - Pros and Cons
Client Credentials Flow
| Advantages | Disadvantages |
|---|---|
| * Fast authentication without user interaction * Ideal for automated processes * Easy to implement for M2M communication | * No user access, hence less control * Insecure if token is compromised * No individual user authentication possible * No user consent or rights |
Authorization Code Flow
| Advantages | Disadvantages |
|---|---|
| * Allows the user to maintain control over access * User consent increases security and trust * Flexibility if user access is required later | * Requires user interaction, which can slow down the process * May not be suitable for automated processes * More complex to implement than Credential Flow * User interaction may be unnecessary in some cases |
