Bcrypt vs Argon2

Developers should use Bcrypt when building applications that require secure user authentication, such as web apps, APIs, or any system storing sensitive passwords meets developers should use argon2 when implementing secure password storage in applications, as it provides strong protection against brute-force and side-channel attacks. Here's our take.

Bcrypt

Nice Pick

Developers should use Bcrypt when building applications that require secure user authentication, such as web apps, APIs, or any system storing sensitive passwords

Pros

• It is particularly valuable in scenarios where password security is critical, like financial or healthcare applications, as it mitigates risks from data breaches by making password cracking infeasible
• Related to: password-security, cryptography

Cons

• Specific tradeoffs depend on your use case

Argon2

Developers should use Argon2 when implementing secure password storage in applications, as it provides strong protection against brute-force and side-channel attacks

Pros

• It is particularly valuable in web applications, authentication systems, and any scenario where user credentials need long-term protection, such as in databases or authentication servers
• Related to: password-hashing, cryptography

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Bcrypt is a library while Argon2 is a tool. We picked Bcrypt based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Bcrypt wins

Based on overall popularity. Bcrypt is more widely used, but Argon2 excels in its own space.
