Both are grammatically correct. But "no registration required" is more commonly used. The following sentences can be used interchangeably:
No login required
No sign up required
No registration required
No registration needed
Either is OK.
When you are faced with this kind of decision and you want to get it right, it is often the case that the oldest and shortest words are the best. Also, it is a good idea to avoid words with Latin and Greek roots and favour words with Germanic or Old English roots, since they tend to be simpler and easier to understand.
In your case, you have need, which has a Germanic root, and require, which has a Latin root.
I'd choose needed, but it's up to you.
There is not so much difference, but the reader's perception may vary. You have to try to understand what their expectation is.
no registration needed
This is rather informal and could be used in most situations. Some functions, such a downloading software or reading a blog, often do not require any registration. In these kinds of situations, this phrase is enough.
no registration required
This should apply to situations where registration would normally be required, for example to get an email account. Your condition (not needed) would be considered exceptional and important for the customer to understand.
