I have been doing backend dev for 3 years now, i read couple of articles recently which says argon2 is much more safer than bcrypt everyone should switch to it.
Is it still safe for large production applications with a large user base to use bcrypt as the password hashing algorithm or should it switch ?
SO there is no need for changing it if i am using the bcrypt out of a std library like device for rails or passport for node ?
I can't guarantee you that. You should read to understand best practices to use bcrypt and make sure you are following all of them.
The problem with bcrypt is that, it's very secure if you know what you are doing. Select the wrong parameters and you can screw everything.
On the other hand, newer implementations will not allow you to selece insecure hashes and being easier to use.
