    Quick update! Starting today I've added the option to add your cell phone number to your account.

    Completely optional, of course!

    So why would you want this? Well, it's a backup way of accessing your Pinside account when your e-mail is not working properly (or if you can't access it).

    Example: you're on the road, trying to log to Pinside. You get emailed a login verification code, since you're on an unknown/new IP address. Oops, you cannot access your (work) e-mail. Luckily you have added your cell phone # to your account, so you can now hit the "send SMS instead" button and the code will be texted to you.

    This it's stil the alternative_ login method, secondary to e-mail. Why? Simple: it's free. Yes, an SMS costs less than a cent, but with thousands of logins every day, it still adds up

    Keep in mind, if you don't log out on your device and visit Pinside at least once a month, you should never be asked for a login code.

    PS: Even if you're not adding your cell phone number, please double check that your e-mail address is correct. I still get too many messages from folks who no longer have access to their e-mail - it's quite a hassle.

    I'm getting this when I try to add my number:

    I am being asked to provide a verification code every time I sign in.
    I receive a message that this is a new IP address and it sends a code to my email .
    This has only started happening this last few weeks.
    What’s changed?

    After reading the thread
    I guess this is the new normal
    I thought it was a error since my IP address hasn’t changed

    Can't add my cell number either, just tried at least 5 times. Same error message as above.

    Quoted from Moonshot:

    Aha! Actually a few people contacted me, telling me the exact same thing: how they were surprised to get a login code request when their IP address didn't change.

    Turns out that many of you (me too in fact) have two IP addresses. One IPv4 and one IPv6. Which one gets used seems to be almost random. Sometimes you'll get connected to Pinside on v4 and sometimes on v6. I'm not a network expert, so not sure when, why or how this is determined. Maybe someone can chime in?

    So you might think you are connected via your 123.456.789.123 IPv4 address when in fact you're connecting with a different IPv6 address every day.

    At least, that's what I found out. I never knew this myself.

    Here, check out my last few IPs and notice how most are IPv6, while there's also one IPv4 visit there:

    This is all from my home, all connections made today. My IPv6 changes very often!

    (Sorry, I greyed out the full addresses, but they're all slightly different.)

    FYI, I'm currently investigating ways to allow for *slight* IP address changes. For example, if your IP address closely matches a previously used IP address (same "network part" I think is what it's called) I could allow the login automatically. So, for example, I could check if the first two number groups of your IPv4 are the same and then let you log in without a login code request. For IPv6 I think it's the first 4 alphanumeric groups. Again, i'm not a network expert so i need to look into this some more.

    Quoted from SonicZone:

    Yeah, I'm not sure either. There's some weird stuff going on sending SMS to USA/Canada. It has to do with new rules that got introduced at the end of 2021. Twilio (my sms provider) is asking me to pay them a bunch of money to get my business verified and to purchase a toll free numbe. It's all very incomprehensible.

    If you could please PM me your cell phone number, I can try to send you a test SMS from my other provider (Clicksend) and see if that works better.

    For a quick workaround -- can you change your infra (load balancer) to support only ipv4? Did a quick search and it looks like the protocol is to attempt to use ipv6 if it's available on both sides and fall back to ipv4 if it's not.
