Do you know applications where you only log in through a link received by email?


Hi there

I'm wondering if you've ever used applications where you only connect via a link received by email. If yes, which ones? Does this seem like a good way for you?

    Substack does this.

      Thanks, I didn't know about substack

  2. 1 does it as well. I like it, but sometimes I have to wait for the email a couple of minutes and that is annoying.

      I think this is the biggest downside of 'email link only' login functionality. You have to ensure that your transactional email service is super reliable and blazing fast.

      Thankfully the services I use that have this facility usually provide the link within a few seconds. It would be majorly frustrating to have to wait minutes or sometimes not have the email turn up at all.

        Yes, you're right, the mail service must be rock solid. Otherwise the desired UX would turn against us!

          I will also argue that there could be issues with the email provider, issues with the internet being spotty. Lot's of issues. I would give the people both options because remember, not everybody has high-speed internet.

    Hi @vincentoff I do that with all my apps. It's really nice because it verifies emails and you don't need all password recovery and all that. However I did have some complains so I recommend to add also social login like Google with it.

    It's particularly useful if you have a per user pricing because it's hard to share one email.
    I use JWT tokens for it. Let me know if you need more details on the specifics.

      Thanks for your feedback @cosbgn! It's interesting, can you share with me your apps ? I know the JWT tokens, I also use them but not yet to generate temporary login links

    FullStory does this, as does EnvKey. I use and love both tools, and don't think this is a problem at all - Sometimes, especially on my mobile when I don't have my password manager handy, it is a really cool way to get into a service quickly.

    I believe Slack and MailChimp also offer this as an optional login method outside of the standard username/password.

    slack's magical link?

      Yes you're right, as much as I love Slack I don't think their magics link user experience is that great. How often do you use it?

    Token authentication is quite cool - especially for low engagement products, where you don't want to subscribe to. The Wordpress plugin s2member offers such a token authentication for the sale of temporary access. Do you plan to implement it somewhere?

      Thanks I didn't know s2member plugin. That's interesting!
      In my case I'm thinking about implementing it in a privacy based electronic signature application:
