This is so fucking stupid. There is no way to update the logo of a custom social connection on Auth0 without using the command line. On literally every other service I've used, there's a little box to upload a logo. But Okta have a funny idea of what developers want. And, to make matters worse, their documentation contains an error! They don't listen to community requests or take bug reports,…

Let's say you have a website - your_website.tld - and you want people to log in to it using their Mastodon account. For a traditional social-media site like Twitter or Facebook, you would create an OAuth app on the service that you want. But there are hundreds of Mastodon servers. So you need to create a new app for each one. That sounds hard, but it isn't. Well… not too hard. Here's some c…

Imagine the scenario. You're trying out some cool new Twitter app. It asks you to sign in via OAuth as per usual. You look through the permissions - phew - it doesn't want to access your Direct Messages. You authorise it - whereupon it promptly leaks to the world all your sexts, inappropriate jokes, and dank memes. Tragic! What's going on? Many years ago the official Twitter API keys were…

Twitter have just released Periscope for Android. I'll do a full review of it later (tl;dr it's Qik with worse resolution) - but for now, I want to focus on the sign up process. You can only sign in with Twitter. That's fine, it's a Twitter product. So I pressed the sign-in button and this is the screen I saw. Is that the Twitter mobile website embedded into the app or is it a phishing…

OAuth was designed to combat an anti-pattern. Typing your username and password into a third party site is bad idea. A really bad idea. I mean, you may think it's a bad idea to give your bank details to a Nigerian prince but that's just peanuts compared to giving away your password to an untrusted site! So, that's why we use OAuth. Rather than handing details to a random site, we authenticate…

Why doesn't Twitter's OAuth let me specify the length of time a 3rd party has access to my account? Take a look at all the crap you've given access to your Twitter account. Are you ever going to use that "See how many of your friends like cheese" app again? No. Long time readers will know that I have some severe usability and security concerns with Twitter's OAuth implementation. See also my …

I am no longer confused! Here is a quick tutorial in how to post images to Twitpic and Twitter when using OAuth. I'm indebted to Steve Corona of Twitpic, for his help with this. You can see the full code on Dabr's Google Code page. First of all, you'll need to have enabled OAuth for your Twitter client. I use Abraham's excellent OAuth libraries for PHP. This tutorial assumes you already…

Twitpic has implemented an OAuth API. No more having to hand out passwords to all and sundy. Only I'm too much of a dunderhead to get it working. Perhaps it's a combination of heatstroke or this rotten head-cold, but I just can't see what I'm doing wrong. Any help much appreciated. The easy bit. It's easy to post the data to Twitpic $media_data = array( 'media' =>…

This morning, when I logged on to Twitter, I saw a user who I didn't recognise tweeting away in my timeline. I wracked my brains thinking about how they could have gotten in there before I realised it was a long-dormant friend who had changed their name and avatar. But, in thinking about how a spammer could infiltrate one's timeline, I think I came up with a fairly bullet-proof method to spam…

Twitter have announced that all third party site will have to use OAuth. You will no longer be able to just type in your username and password to get access to Twitter via your favourite web client. Usually, I would be a big fan of this move - especially if it forces password anti-pattern sites like TwitPic to implement the new, secure standard. This means that you won't be able to log in to a …

I'm a big fan of OAuth - despite some claims to the contrary. It's an excellent way of teaching people not to stick their username and password into any old site which asks for it. Which is why I'm so incredibly disappointed in Twitter's implementation of mobile OAuth. For a service which started out operating by SMS, Twitter takes a surprisingly unenlightened view of mobile. It's main mobile …

Twitter has a gaping security hole. Changing your password won't stop malicious users logging in as you! I received a rather worrying email from Twitter. Apparently they thought my password had been compromised and needed to be reset. Reset Your Twitter Password After checking to see if it was valid, I went and changed my password. Any site which relied on a cookie to post to Twitter would h…
