### AI overview

This comparison examines 1Password and Keeper as enterprise password managers. It covers credential storage and sharing, included features and add-ons, guest access, AES-256 encryption, local decryption, zero-knowledge architecture, and 1Password's Secret Key and PAKE protocol.

### Source excerpt

Enterprise password managers (EPM) like 1Password, LastPass, Dashlane, and Bitwarden help you create, store, and fill strong passwords and credentials across different websites and apps, so you don't have to remember or write them down. EPMs provide secure sharing, data encryption, and data breach prevention against phishing and malware, helping IT and Security teams protect and enforce policies around credentials. While there are many EPM options, choosing the best password manager can be a challenge. A side-by-side comparison helps you see which is best for your organization's cybersecurity strategy. If you're comparing 1Password and Keeper, it helps to start with what both products are built around: an Enterprise Password Manager (EPM). EPMs are how both platforms store, share, and enforce policies around credentials. They're the foundation for each vendor's broader security strategy. Below is a comparison of core features many organizations consider essential for protecting employees and their credentials. Feature Comparison Credential Management Enterprise password managers store and encrypt users' login credentials to discourage password reuse and insecure storage (like spreadsheets or sticky notes). They typically include a password generator and enable secure sharing among authenticated employees. Both 1Password and Keeper cover these basics. The differences tend to show up in what's included by default versus sold as add-ons. In many deployments, 1Password includes critical capabilities as part of the standard product, while Keeper packages some features as paid add-ons. 1Password also includes 20 guest accounts with every business plan, which can be useful for securely sharing vault access with contractors, auditors, or temporary collaborators. Keeper does not offer equivalent guest access to vaults; sharing is generally limited to users provisioned within the same account. Encryption Both Keeper and 1Password EPM use AES-256 encryption. With either servic

### AI overview

1Password announces Automated Provisioning hosted by 1Password, alongside enterprise multi-tenancy, verified emails, an OAuth-based Users API, and Security Automation integrations for its Enterprise Password Manager.

### Source excerpt

Modern enterprises aren't just adding employees; they're adding subsidiaries, multiple teams, contractors, AI builders, temporary projects, and new SaaS tools every week. And every new addition to a company's ecosystem also brings more credentials to manage. Unfortunately, not all of those credentials can be managed by solutions like single-sign-on (SSO) or privileged access management (PAM). Many of them might be stored in shared spreadsheets, developer environments, browser sessions, and automation workflows that traditional identity security systems were never designed to govern. This results in identity sprawl, operational drag, and an overall widening of the Access-Trust Gap. In the face of this ever-expanding attack surface, security leaders are left struggling to deploy credential security across every team and workflow, without having to build more infrastructure just to manage their infrastructure. In light of these issues, today we're introducing a new evolution for 1Password Enterprise Password Manager (EPM): enterprise-grade provisioning, structure, governance, and security automation built directly into the platform. This launch includes: Automated Provisioning hosted by 1Password Enterprise multi-tenancy Verified emails from 1Password OAuth-based Users API and new Security Automation integrations Together, these capabilities make EPM easier to deploy, easier to scale, and easier to operate as the foundational tool of modern identity security. Introducing Automated Provisioning, hosted by 1Password Automated Provisioning hosted by 1Password is our next-generation provisioning solution, built directly into 1Password. Automated Provisioning requires no servers to deploy, no bridge to maintain, and no ongoing infrastructure burden. In early testing, the response from admins was immediate. "We were done in about five minutes. We set everything up from scratch, added the integration in Okta, and it worked immediately. Adding and removing users was seamless.

### AI overview

Signal is introducing opt-in Secure Backups, initially in the latest Android beta, to let users restore encrypted message history after losing or damaging a phone. The feature is planned for iOS and Desktop, with free text-message and limited media backups plus a paid plan for extended media history.

### Source excerpt

In the past, if you broke or lost your phone, your Signal message history was gone. This has been a challenge for people whose most important conversations happen on Signal. Think family photos, sweet messages, important documents, or anything else you don't want to lose forever. This explains why the most common feature request has been backups; a way for people to get Signal messages back even if their phone is lost or damaged. After careful design and development, we are now starting to roll out secure backups, an opt-in feature. This first phase is available in the latest beta release for Android. This will let us further test this feature in a limited setting, before it rolls out to iOS and Desktop in the near future. Read more...

### AI overview

This article explains zkSNARKs through four main techniques: encoding computations as polynomial equations, reducing verification through random sampling, using homomorphic encoding or encryption, and preserving zero knowledge by masking encoded values.

### Source excerpt

The possibilities of zkSNARKs are impressive, you can verify the correctness of computations without having to execute them and you will not even learn what was executed - just that it was done correctly. Unfortunately, most explanations of zkSNARKs resort to hand-waving at some point and thus they remain something...

### AI overview

This tutorial explains how zero-knowledge proofs extend beyond graph isomorphism to problems in NP, using cryptography to let a prover convince a verifier without revealing the secret knowledge behind the claim. It introduces examples including boolean formulas, subset sums, graph 3-coloring, and boolean circuits, and describes an implementation of a proof for graph 3-colorability.

### Source excerpt

Last time, we saw a specific zero-knowledge proof for graph isomorphism. This introduced us to the concept of an interactive proof, where you have a prover and a verifier sending messages back and forth, and the prover is trying to prove a specific claim to the verifier. A zero-knowledge proof is a special kind of interactive proof in which the prover has some secret piece of knowledge that makes it very easy to verify a disputed claim is true.

### AI overview

This primer explains zero-knowledge proofs through the graph isomorphism problem. It introduces the roles of the prover, verifier, and simulator, and describes graph isomorphism using vertex-label permutations.

### Source excerpt

In this post we'll get a strong taste for zero knowledge proofs by exploring the graph isomorphism problem in detail. In the next post, we'll see how this relates to cryptography and the bigger picture. The goal of this post is to get a strong understanding of the terms "prover," "verifier," and "simulator," and "zero knowledge" in the context of a specific zero-knowledge proof. Then next time we'll see how the same concepts (though not the same proof) generalizes to a cryptographically interesting setting.

### AI overview

Brendan Eich reflects on privacy, user data, and the concentration of power in network-driven markets. He proposes exploring client-side and private-cloud systems, zero-knowledge proofs, and protocols to give users more bargaining power and economic value.

### Source excerpt

Slides for the brief talk that I gave at a Harvard seminar on privacy and user data organized by John Taysom last week. My talk was really more about the "network problem" than the "protocol problem". Networks breed first- and second-mover winners and others path-dependent powers, until the next disruption. Users or rather their data ... Continue reading "The Next Mission"
