Linking your number to message ReminderIt on WhatsApp

To text ReminderIt on WhatsApp there is nothing to link in advance: the number you message from becomes your account. Here is how that works and why it matters.

The WhatsApp chat feels casual, but it is doing something serious: reading and changing the reminders on your account. For that to be safe, ReminderIt has to be certain the person messaging is really you. It does that by using the number you message from as your account.

This post explains what "linking" your number means today, how the link is formed, and what happens the first time a number messages in.

Why a link is needed at all

WhatsApp identifies you by your phone number. ReminderIt uses that number as the key that ties the conversation to your account, so when you say "cancel my 8am call" it knows whose 8am call to cancel.

Without that link, the assistant would have no safe way to tell one person's reminders from another's. Your number is the anchor that makes the whole chat personal to you.

What verifying actually does

WhatsApp already verified your number when you set WhatsApp up on your phone, so there is no separate code, form or website step. From your very first message, messages arriving from that number are treated as coming from you, and the assistant acts on them.

There is no login step each time. You simply open WhatsApp and start typing.

If your number is new to ReminderIt

Message from a number ReminderIt has not seen before and it simply gets you started: your number becomes a new account with a 7-day free trial, no card and no app needed. Nobody else's reminders are visible to it.

This keeps things personal: every action in the chat can be tied back to the phone that sent it.

Setting the link up

You: Hi, can you set a reminder for me?

ReminderIt: Of course! Just tell me what and when, for example "remind me to take my tablet at 8pm every day".

You: Remind me to call the bank tomorrow at 10am

ReminderIt: Done. I'll call you tomorrow at 10:00am, and you'll get a WhatsApp message too.

That first message is the whole setup, and the assistant gets straight to work.

Keeping the link secure

Because the link rests on your number, keep your phone locked and consider turning on WhatsApp's own two-step verification. You can reply STOP at any time to opt out of messaging, and if you like, log in at reminderit.com with WhatsApp or Google to see your reminders, history and settings.
