This is the correct answer. Just because the norm is to embed verification hashes in URLs to be clicked, doesn't mean it's the right way for it to be done.

Why not send a short random code by email for the user to then copy into the sign-up form they were in the process of filling in?

It takes more effort and more users will decide to move elsewhere. I don't really believe that if someone can't bother to copy code from e-mail, he's worthy to have as a client, but some company are obsessed by metrics and percentage of successfully registered users is one of those metrics.

I understand your way of thinking, but we ended up having a flow for a government site where users had 2-3 steps what normally could be done in 1. Also many were not tech savvy and confused. So we ended up adding JS to automate the click.

You automated a click on a government website? So tell me: how'd that audit go?

This depends on your willingness to turn away business, and may not even be legal depending on where you work. In the United States, I would not want to defend that copy and paste scheme as being compliant with the Americans With Disabilities act having seen usability tests from people trying to accomplish that exact workflow using screen readers. Remember that things like cognitive impairments count and, like vision and motor control/range of motion, most of us will be affected at some point in our lives.

What I do think would be reasonable is having a well-labeled link which takes you to a confirmation form: someone can follow it easily and choose to submit it with far less friction and it leaves standard web semantics intact.

Clicking a link (one action) is easier than copying a code and pasting it (two actions). It's possible the user will copy the wrong thing or paste the code into a wrong field, including the browser address bar.

All of that may affect the sign-up rate.

Kinda. I often read my email on my phone while working on my desktop. (Or visa versa). In these situations, a code is always better. I hate the links personally.

How many times having to click a link (instead of entering a code) stopped you from finishing a sign-up process?

Nobody remembers the exact moment they stopped thinking about something because it was easier not to.

Ragequitting is one way to exit a process, but just not going to the next step from distraction is surely more common.

I'm asking because often when I talk to people about things they hate, they end up admitting it's not that big of a deal. The annoyance is minor enough they don't look for alternatives or abandon whatever they were doing.

The original discussion was about clicking links vs reading and entering the code in sign-up confirmations. The former takes less steps and is easier to complete. Power users with unusual habits might disagree. But if they complete the sign-up anyway, it makes more sense to focus on regular users.

It’s pretty easy to measure. I had a site with a verification step. And we would see like 20% drop off of people who clicked on the link but never confirmed. Not sure why. We didn’t have them copy and paste anything, just click a confirm button.

Switching to no confirm obviously changed this to 0% drop off of people who clicked the link, but the number of people who clicked was the same.

It was curious to me why people wouldn’t go through with the confirmation step, but never learned why. We just learned that for some reason more people click once instead of twice.

How would you have known if that 20% were real people and not bot activity?

I don’t necessarily. But they have active accounts that do stuff and had the drop off activity consistent with “normal users.”

So it doesn’t matter to me if they were bots or not.

For example, 100 users clicked on the first link, 80 completed, and had normal account activity (clicking on stuff, uploading and downloading things, etc).

100 users clicked on the second link and then had normal account activity.

Maybe they were all bots, but they seemed human based on the “normal activity.”

> user to then copy into the sign-up form

Extra steps are hard and boring and people don’t want to do them.

I consider myself a savvy user and I want to click a link. Not click a link, then look up a code from the email, then paste, then click submit.

I’d live with having to manually click “I’m sure I want to unsubscribe” or something.

This is most annoying when the site wants me to type in my email address to unsubscribe. I have lots and lots of different email addresses that funnel into a single one. When the site doesn’t put my address in the “To” field, I dont know who they sent to.

Services should be respectful of users time.

Are we really going to continue to break the paradigm that GET requests should be idempotent to save people an extra click or Ctrl+C and Ctrl+V? Standards matter. In this case Google are doing something that should be allowed, but being criticised for it because it breaks badly implemented services.

Entering emailed or texted codes is becoming more common with 2FA for banking, PayPal etc. anyway so I think most people are going to broadly manage.

Sorry, GET requests aren’t idempotent. At the minimum they create log entries. So you can DDoS servers by filling their logs with “idempotent” GETs.

UX is important, and I think saying “suck it users, I’m going to use GET the way I think is write” is not a positive way of thinking about it.

I think the problem is just the mechanics of POST not being allowed in an email, so if there’s a way to POST from just clicking on a link I think we should use it. But there’s not, so having a GET that triggers something is the least bad thing. I like it better than javascript and forms in email. And better than autosubmitting, hidden forms on load.

There were good suggestions in other comments in this HN post.

One of them mentioned that you can continue keeping things as a 1 click solution with the token in the URL, but instead of doing the destructive action upon visiting the link -- instead you would get sent to a page with a form where the token is put into a hidden field that gets auto-submit as a POST request with Javascript.

This way from your POV it's a 1 click solution. You only waste a second waiting for the redirect and if the user doesn't have Javascript enabled you can <noscript> the field as being an input field which is pre-filled out based on the value from the URL (this can be done server side).

Now everyone is happy, unless gmail is going to go as far as auto-following redirects with JS enabled.

Ideally they wouldn't be following redirects _if they're POST requests_, right?

True, that was a bad choice of words but gmail could still load the page, execute the JS which in turn submits the form which is a POST request to your back-end. It's technically not following a redirect but it's doing things beyond just visiting the URL linked in the email due to it executing JS.

Ah interesting, so you're saying that GMail is not likely to be avoiding the POST requests if they're in the JS code? I have a passing, non-professional familiarity with Web practices, so this isn't something I have a great intuition for.

The basic flow would be:

    - You GET /reset/abc123
    - Your server responds back with a page that has a form
    - There's a hidden field with the token
    - Javascript kicks in and on page load executes the form as a POST request
    - Your server responds to that POST request and does whatever it needs to do

All of that is kicked off by gmail visiting /reset/abc123, and now it comes down to whether or not gmail's pre-visiting code will run the JS on the page. If not, then the above workflow fixes this issue, if it does then you're in the same position as avoiding all of this and having a GET /reset/abc123 perform the destructive action.

Right, it's the second part of the fourth bullet that I was asking about. Basically, that it sounds like it isn't feasible for Google to avoid POST requests if they're being submitted from JS.

>This is most annoying when the site wants me to type in my email address to unsubscribe.

I've become increasingly suspicious of this practice

if my email address is in the URL, why don't you autofill that email box for me? if it's not in the URL, why aren't you fetching it from your database using my unique hash in the URL? do you even keep any records of email subscription preferences? am I just signing up for more shitty spam by giving you my email, again? am I just being marked as 'active' i.e. fresh meat, somewhere in the spammiverse?

these questions become more poignant and the suspicion more fiery when, low and behold, it turns out you are still subscribed

I don't fill them in any more, I just block the sender

don't get me started on the "it may take up to 28 days for our systems to register your desertion" bollocks -- I'm not working a contractual notice period, or running a lap of dishonour. it's a bitflip to 'false' in the 'is_pesterable' column, else a respectful deletion. it takes microseconds, not weeks!

That too as I suspect the unsubscribe links may just be data gathering.

I typically never type in any information because I assume the site doesn’t know and wants to know.

I’d rather just set up a kill rule on my end than risk getting my email on one more list.

Verification hashes in URLs are fine, as long as accessing the URL does not invalidate the hash yet.

This is how Steam does it.
