An expired certificate is a total outage with extra embarrassment: the site is up, but every visitor is told to run. The fix is a renewal you forgot.
Set this reminder on WhatsAppTo set an SSL certificate expiry reminder on WhatsApp, text NagMeLater "Remind me on 10 August to renew the SSL certificate", or tap a button below to send it in one tap. The bot confirms the schedule and nags you at the right moment. No app, no signup, first 5 reminders free.
Edit to your cert's date, buffer included.
Verify the auto-renewal actually renewed.
For paid certificates renewed annually.
Modern certs from Let's Encrypt expire every 90 days by design. The design assumes automated renewal, and automation assumes someone checks it still works.
The cron job broke during a server migration two months ago. Nothing alerts you, the old cert is still valid, until day 91 at 3am.
The wildcard cert bought yearly, the internal tool, the load balancer cert uploaded by hand: anything renewed manually is a candidate for the next incident.
By the time an expiry monitor fires, you are in incident mode. A monthly "did certbot actually renew everything" check catches broken automation with 60 days of slack.
The main site is fine, it is the staging subdomain, the API gateway and the mail server cert that lapse. List them once, one reminder each, and the surprise outages stop.
Maximum certificate lifetimes keep shrinking industry-wide, which means more renewals per year, not fewer. The manual-renewal era is ending, your checks matter more.
The button pre-fills it. Plain words, no format to learn, no reminder app to install.
Date, time and recurrence are parsed from your message and confirmed instantly.
Right inside WhatsApp, where you will actually see it. Reply done, snooze it, or edit it any time.
That is exactly who needs the monthly check reminder. Auto-renew works until it silently does not, the nag makes a human verify.
Set up a group and target them: "remind @Ops on the 1st to verify cert renewals". It arrives on WhatsApp, no dashboard login required.
Two weeks for automated stacks, a month for anything involving a purchase order. Certificates can be renewed early without losing time.
Domains, API keys, cloud credits and access tokens. Each is one message: "Remind me on 1 March to rotate the payment gateway API keys".
You do not need one. NagMeLater works inside WhatsApp itself, so there is nothing to install, update or remember to open. Text it "Remind me on 10 August to renew the SSL certificate" and the reminder exists. The best SSL certificate expiry reminder app is the chat app you already check all day.
The button opens WhatsApp with "Remind me on 10 August to renew the SSL certificate" already typed. Send it, and it is handled.
