I just have a simple LAMP server and I don't really understand Apache. How do I make it "https"?
http://www.startssl.com/ will give you a free SSL cert.
They've got a "How to install" section that specifically deals with Apache (and another one which deals with WHM/cPanel if you're using that for your LAMP management).
It's less than an afternoon's work to get up to speed.
Note that you'll need a dedicated ip address (or you might settle for a server running new enough versions of Apache to use SNI - http://wiki.apache.org/httpd/NameBasedSSLVHostsWithSNI - but that'll still not work for IE6 and very old versions of other browsers - pre 2.0 for Firefox)
There are basically two steps, both of which can be at no additional cost:
1. get a certificate, and
2. configure your server to use the certificate.
You can generate a certificate yourself, without paying anyone, and it will work fine, but some browsers will throw up a warning page if it is not signed by an authority (more: http://www.namecheap.com/support/knowledgebase/article.aspx/...).
You can get free certificates backed by a CA trusted by most browsers, for example at https://www.startssl.com. There are some limitations (e.g. no wildcard certificates) but it's still much better than a self-signed one.
I occasionally quickly cook meals in my kitchen. I never figured out what I should do exactly to set up the dishwasher with detergent, without needing to pay for the detergent.
I just have a simple kitchen and I don't really understand dishwashing. How should I make it "hygienic"?
(That guy would get shut down by the health authorities as soon as he started serving food to the public. Why aren't web developers offering their systems to the public held to basic data safety practices?)
and FTR, I did not grow up knowing how to use dishwashers but was quite aware of the basic relationship between the act of dishwashing and detergents. Extrapolating that fundamental relationship to a dishwasher is to say the least -- elementary.
If you'll allow me to shamelessly self-promote. We make it really easy to do this correctly using an email and password at my startup: https://www.dailycred.com/
In particular, a man-in-the-middle can capture the redirect to DailyCred and instead send the user to some trojaned site to capture their username and password (and then forward it on to you to get a legitimate token, but the password's been leaked in the process).
I don't think it's helpful to say "we do HTTPS so you don't have to". Your users still need to be using HTTPS and preferably HSTS, unless I'm misunderstanding the intended use case. (I'm very happy to see that you guys do HSTS, though!)
Because of this narrow risk, we encourage our clients to still get ssl certs as they grow. However, when they are small MVPish non-sensitive apps with 50 users, the risk of this kind of attack is very small. (For example, Facebook Connect, which has the same vulnerability I described, would be a much more obvious target with a very high payload.)
The way we see it is getting people who are about to either store plaintext passwords or not salt their hashes correctly or pass them over non-https (like HN by default, boo!) or mess up a dozen other things, we're much more secure.
1. It's a shitty UX
2. There are more people without an OAuth provider than there are with them
3. It's a sure fire way of killing your conversions
4. It means people start getting tethered to providers
5. It's very complicated when it goes wrong
6. THIS DOESN'T SOLVE THE OP'S QUESTION AT ALL. OP POINTS IT OUT. YOU IGNORE OP.
Enabling SSL stops people sniffing sensitive data on public wifis. That's why everyone says enable SSL by default.
Also there's something wrong if you're a programmer and can't afford an SSL cert as it's the same price as a couple of beers.
I also find your password advice extremely questionable, it just doesn't make sense to me.
As for making it https, (hypothetical web developer) most cheap hosting providers actually provide tools for managing certs and apache configs in cpanel. It's not too difficult to do yourself. Basically install mod_ssl and copy paste a standard config, substituting the pathnames for the paths of the certs you got from a CA.
I understand that your average beginning-throw-up-a-website-for-a-business would find this difficult, but they can hire someone for an hour to install their certificates.
Wtf guys? Didn't we /just/ do this about GoDaddy? Just say NoDaddy.
