Step by step
How RenewOS handles your ssl certificate reminder
- 1
Inventory every certificate
Production, staging, admin panels, mail servers, API gateways — the certs nobody remembers until the pager goes off. One item each, one calendar for all.
- 2
A ladder tuned for short-lived certs
For 90-day certificates a 90-day reminder is useless. This tool defaults to 30/14/7/3/1 days — dense enough for Let's Encrypt, calm enough for annual certs (override per item).
- 3
Renew, then verify the cycle
Mark renewed with the new expiry; the schedule resets automatically and the old cycle is preserved as history. Teams on the Business plan get audit logs of who did what.
Questions
About the ssl certificate reminder
I use auto-renewing certs. Still useful?+
Yes — auto-renewal fails silently (expired API tokens, DNS changes, failed hooks). RenewOS is the independent check that catches what automation missed.
Can different certs have different ladders?+
Yes. The default offsets are per-tool suggestions; every item's reminders can be toggled and overridden individually.
Is this a monitoring service?+
No. RenewOS doesn't probe your endpoints — it tracks expiry dates and reminds humans. That's why it's private, cheap and never the thing that breaks.
