Use a login/auth system or do it myself?

[eluser]Sinclair[/eluser]
Hi,

I need to do a simple register/login system to use in an Ads application. Should I do the login system myself or should I use an auth system?

Witch auth system should I use? Benefits of developing myself or use an ready to use auth system?

Ps: Sorry my bad english.


Best Regards,

Here are two libraries that I can confirm worked well for me in test projects and am considering for deployment to actual production.

They both lack a lot of documentation in terms of pretty reference guides but they are both EXCELLENT at their code comments. You can more or less read along in their code comments and get a good feel of how things work along with the included demos.

A benefit of using a system already developed is that others will likely use it and find bugs or problems. In a system we design ourselves and use ourselves, we may never see the bugs or anticipate use cases that others do.

I don't know too much about some of the other systems but having looked over them and downloaded several auth libraries over the past few months to evaluate, I can tell you that the two listed appear to be much lighter weight to implement (and upgrade over time).

Built it yourself .
It may take a bit more than using other already created but the advantage is that you gain experience + you can use YOUR OWN library in later projects + it never gets unmaintained as most of these libs do .
If it has a quirk you will be able to find it faster then you will do it on other libs etc . So , on long term it's a huge advantage .
