We have a web app with a Java backend. Currently we have a simple username / password login/sign-up page (on sign-up you also enter an email).
We want to implement a 'forgot password' functionality, and on sign-up an email verification functionality.
Should I implement it myself, or are there Java packages/SDKs which do that for me?
(I think there must be - because it is a very common functionality - but I didn't find any)
