Cipherwill is a digital will platform that monitors your activity and delivers your vault to beneficiaries when you stop checking in. AbsentKey is a sharing vault where recipients request access to individual secrets, and you control the response window. Same problem, different mechanics and the right pick depends on how you think about sharing.
Same problem, different products
If you’ve been looking for a way to get your passwords, accounts, and files to the right people when you can’t hand them over yourself, the emergency access space has a few options. You’ve probably come across Cipherwill. They’ve published more blog content about digital wills and dead man’s switches than almost anyone else in the space. They’ve been at it longer and they know the problem well.
We built AbsentKey, so we’re biased. But both products deserve an honest look because they’ve taken very different approaches to the same underlying problem. Cipherwill built a digital will. AbsentKey built a controlled sharing vault. Those aren’t the same thing, even though they overlap.
This post walks through what each product does, where they differ, and when you’d pick one over the other.
Quick comparison
# trigger model cipherwill → “check in monthly, or vault delivers” absentkey → “recipient requests, owner has window to respond”
# sharing unit cipherwill → entire vault to beneficiaries absentkey → per-secret, per-person, per-timer
# surface cipherwill → web only absentkey → ios + android
# pricing cipherwill → $5/mo or $40/yr premium absentkey → $0.99/mo or $9.99/yr (receiving free)
What Cipherwill does
Cipherwill is a digital will platform. You store your important information passwords, account credentials, crypto keys, legal documents in an encrypted vault, designate beneficiaries, and the platform monitors your activity. Stop logging in or updating your profile for long enough, and Cipherwill treats that as a signal that something’s happened to you. It starts delivering your vault contents to your beneficiaries.
The encryption is solid. Cipherwill uses AES-256 along with what they call Time Capsule Encryption, adding a time-based layer so your data stays locked until the right moment. They’ve open-sourced their client code, which means you can verify how encryption works before data leaves your device. That matters.
They support a broad range of digital assets: cryptocurrency wallets, social media accounts, investment details, insurance info, legal documents. The whole platform is designed around the will concept you’re organizing your entire digital life and specifying who gets what after you’re gone.
The check-in system tracks your activity on the platform. Logging in, updating your profile, adding data, all count as signs of life. Every few months (based on your interval setting), you’re expected to review and update your information. Miss that window, and the delivery process starts.
Cipherwill’s content marketing is impressive, by the way. They’ve published guides on digital will setup, business use cases, family planning, and security. If you’ve been reading about dead man’s switches online, their blog was probably one of the first results you found.
Free plan: limited segments, up to 5 beneficiaries. Premium: $5/month or $40/year for full access and unlimited beneficiaries.
A check-in watches you. A request watches the moment someone needs you.
What AbsentKey does
AbsentKey works differently. Instead of a digital will that triggers on inactivity, it’s a vault where you share individual secrets with specific people, each with their own access rules.
You create a secret (a password, a seed phrase, a PDF, an image). Assign it to a recipient. Set a waiting time for that person, anywhere from 1 to 365 days. Done.
When a recipient wants access, they open AbsentKey and send a request. You get notified. You can approve right away, deny it, or do nothing. If you don’t respond before the timer runs out, the recipient gets access automatically.
Here’s the big difference: nothing happens until someone asks. AbsentKey lets you share passwords without giving access upfront. It doesn’t monitor your activity or ping you to prove you’re alive. The system sits idle until a recipient initiates a request. No false triggers from missed check-ins, but your recipients need to know they should request access when the time comes.
Each secret is independent. Your spouse might have access to bank passwords with a 14-day timer. Your business partner gets server credentials with a 7-day timer. Your sibling has a crypto seed phrase on a 90-day timer. Different secrets, different people, different timers. You don’t hand over everything to everyone.
Everything is end-to-end encrypted (XSalsa20-Poly1305, X25519, HKDF-SHA256). The server never sees plaintext. The mobile client is source-available so anyone can audit the crypto.
Receiving is free. Your trusted contacts download AbsentKey, accept the invitation, and they’re set. Creating and sending secrets requires the premium plan, $0.99/month or $9.99/year.
Key differences
Check-in monitoring vs. request-based access
This is the core difference. Cipherwill monitors whether you’re still active. Stop showing up, and it triggers delivery. AbsentKey doesn’t monitor anything it waits for a recipient to ask.
Both have trade-offs.
Check-in systems can fire accidentally a long vacation, a forgotten login, a busy stretch. Request-based systems can stay idle if recipients don’t know to ask. Pick the failure mode you can live with.
Check-in systems can fire accidentally. We cover the difference in depth in our emergency access vs dead man’s switch breakdown. Long vacation without internet, new phone and you forget to log back in, or just a busy stretch where you ignore the reminder. If the check-in window passes, delivery starts whether you meant it to or not. Cipherwill’s intervals are in months rather than days, which helps. But the risk isn’t zero.
Request-based systems depend on the recipient knowing to ask. If your spouse doesn’t know about AbsentKey, or doesn’t realize they have access to specific secrets, the system doesn’t help. You need to have a conversation upfront: “If something happens to me, open AbsentKey and request access.” That’s a coordination step check-in systems don’t require.
Digital will vs. controlled vault
Cipherwill is structured around a will. You organize your entire digital life, name beneficiaries, specify what happens when you’re gone. The mental model: “Here’s everything. Deliver it when I’m not around.”
AbsentKey is structured around individual secrets. The mental model: “Here’s this specific thing for this specific person, with this specific waiting period.” More granular, less all-encompassing. You’re not writing a will, you’re setting up individual sharing arrangements.
Want one place to organize your entire digital estate? Cipherwill’s model makes more sense. Want per-item control over who gets what and when? That’s AbsentKey’s territory.
Web vs. mobile
Cipherwill is web-only. No native mobile app. Works on any device with a browser, but no push notifications for time-sensitive events.
AbsentKey is the opposite: mobile-only, no web app, no desktop client. Push notifications land instantly when someone requests access, which matters when there’s a ticking timer.
Laptop person? Cipherwill. Phone person? AbsentKey.
Pricing
Both land in a similar range. Cipherwill has a free plan (limited segments, 5 beneficiaries) and premium at $5/month or $40/year. AbsentKey is $0.99/month or $9.99/year, with receiving always free.
The structural difference: Cipherwill gives you a limited version of the full platform for free. AbsentKey makes receiving completely free but charges for creating and sending.
Source availability
Both projects have made their client code available for inspection. Cipherwill’s is open-sourced so you can verify encryption before data leaves your device. AbsentKey’s mobile client is source-available on GitHub. Neither lets you self-host the full platform, but both give you enough visibility to check the crypto claims, which is more than most competitors offer.
When Cipherwill makes more sense
You’re doing digital estate planning. Cipherwill is built around the will concept. Organizing all your accounts, assets, and credentials in one place with clear beneficiary assignments that’s exactly what it was designed for.
You prefer working in a browser. Managing things from a laptop, browser-based workflows, no extra app on your phone. Cipherwill’s web-only approach works here.
You have complex inheritance arrangements. Multiple beneficiaries with different roles, estate-style distribution. Cipherwill’s beneficiary system is optimized for this.
Check-ins don’t bother you. If you log into platforms regularly anyway, the check-in model won’t create friction. Cipherwill’s intervals are in months, not days. It’s not a daily chore.
When AbsentKey makes more sense
You want per-secret, per-person control. Spouse gets bank info. Co-founder gets business credentials. Parent gets the iCloud password. Each with a different timer. That granularity is AbsentKey’s whole point.
You don’t want check-ins. Travel a lot, switch devices often, or just don’t want another recurring obligation? AbsentKey’s request-based model skips all of that.
Mobile is your primary device. Native iOS and Android app. Push notifications for access requests, biometric auth, an interface built for phones.
Receiving should be free. Your trusted contacts download the app, accept the invitation, done. They never pay.
You want to read the code. AbsentKey’s mobile client is on GitHub. You (or someone you trust) can audit the encryption yourself.
FAQ
Can I use both?
Yes, and it might make sense for some people. Cipherwill as your digital will for organizing your full digital estate, AbsentKey for specific high-value secrets where you want per-person timers and request-based access. They don’t conflict.
Is Cipherwill’s check-in system reliable?
Their intervals are longer than most competitors (months rather than days or weeks), which reduces accidental triggers from a short vacation or a busy stretch. But any system that equates inactivity with incapacity carries some risk. Make sure the check-in interval matches your actual usage patterns, logging in, updating your profile, or adding data all count as activity.
AbsentKey doesn’t have a web app. Is that a problem?
Depends on how you use your devices. Do most things on your phone? You won’t notice. Prefer managing sensitive information from a laptop with a full keyboard? The lack of a web or desktop client is a real limitation. AbsentKey is mobile-only today. That could change, but worth knowing before you commit.
Wrapping up
Cipherwill and AbsentKey both tackle a real problem: getting your important information to the right people when you can’t hand it over yourself. Cipherwill has been around longer, has a bigger content presence, and has built a proper digital will platform. AbsentKey is newer, smaller, and focused on the mechanics of controlled sharing.
Want a digital will? Cipherwill was built for that. Want a vault where each person gets exactly what you’ve chosen, on a timer you’ve set, with no check-ins and no bulk delivery? That’s AbsentKey.
Both have trade-offs we haven’t hidden. The right choice matches how you actually think about this problem.
