Strengthening PBX security: Passkeys and the Vodia Phone System
Published on:
October 21, 2025
Vodia PBX strengthens security with passkeys, giving users and administrators a secure, passwordless login method that eliminates many vulnerabilities tied to traditional credentials. Passkeys use public key cryptography, storing the private key on the user’s device and the public key on the server, making them resistant to phishing and credential theft. By reducing reliance on passwords, Vodia minimizes the attack surface in cloud environments and makes authentication simpler and more secure, while ensuring a smoother, faster login experience for all users.
Vodia has supported the use of passkeys since 2023, making it possible to log in securely without relying solely on passwords. With Version 69 of Vodia’s best-in-class phone system, passkeys are supported at both the user and administrator level. You no longer need to use passwords with the Vodia PBX, though you may continue to do so if you wish.
Users can also receive a secure login link via email that expires after a predetermined period of time, providing another simple and secure way to access the system.
Security Threats across the Digital Landscape
The current decade has seen a steady increase in cyberattacks, including state-sponsored campaigns and the continued rise of “bad actors” in the digital sphere. While passwords remain a core component of online security, they are also one of the easiest targets for attackers. More robust methods such as two-step verification, security keys, and passkeys provide stronger protection against these threats.
You Need More than Just Passwords
Passwords have been in use for more than half a century and have long served as the “workhorses” of cybersecurity. In today’s IT environment, however, they can’t be the only line of defense - this applies to both individual users and organizations.
Because most passwords are created by users, they are often predictable, reused, or weak. They’re also particularly vulnerable to phishing attacks, which exploit human error. According to a recent Verizon Data Breach Investigations Report:
The human element continues to be a key driver of 82% of breaches, and this pattern captures a large percentage of those breaches. Additionally, malware and stolen credentials provide a great second step after a social attack gets the actor in the door, which emphasizes the importance of having a strong security awareness program.
What Passkeys Are and How Passkeys Strengthen Security
Passkeys are a passwordless authentication method that uses public key cryptography. A private key is stored securely on the client side and a public key on the server side - this means the private login keys can’t be accessed, even if the server is hacked.
Once a user logs in, the website checks whether or not the public key matches up with the private key; for verification, the user is asked to unlock their device using a fingerprint, face scan, or screen lock.
Passkeys offer strong protection against phishing and credential theft. They are stored on individual devices, can’t be guessed or reused, and provide a simple, secure login experience.
Why Passkeys Matter for PBX
Passkeys are particularly effective at reducing risk in cloud environments with multiple users. By eliminating weak passwords, they strengthen security and minimize the attack surface. Vodia introduced passkeys in 2023, shortly after Google, and we remain convinced they are the most secure login method available today. We encourage replacing passwords with passkeys wherever possible.
Passkeys Keep It Secure and Simple
What excites us most at Vodia is how passkeys make our PBX both more secure and easier to use. There’s nothing to memorize, no passwords to reset, and no credentials to steal. Over time, we expect more and more customers will switch to passkeys for their ease of use and security benefits.

Cisco IP Phone Series 6800, 7800, and 8800 devices running Multiplatform (MPP / 3PCC) firmware can be used with the Vodia PBX in SIP-based environments. Supported models span entry-level, mid-range, and advanced devices commonly deployed in enterprise and service provider scenarios. Cisco-provided MPP firmware is used, with firmware versions and upgrades managed through the PBX after initial onboarding, supporting both on-premises and cloud deployments.
Music on Hold plays an important role in how callers experience wait times and perceive service quality. With Vodia PBX Version 70, we’ve enhanced Music on Hold to deliver neutral, calming, high-quality audio that reassures callers while they wait. These improvements, combined with flexible streaming options, emergency messaging, and full support for cloud and on-premises multi-tenant environments, help businesses reduce dropped calls and create a more positive caller experience before an agent ever answers.
Organizations often start with an open source PBX for flexibility, but as systems move from initial setup to daily operations, the real cost becomes management, maintenance, and long-term reliability. This article explores the difference between building a PBX stack from frameworks and running a commercial, integrated PBX platform, focusing on operational complexity, security responsibility, upgrades, and ongoing maintenance. It explains how a purpose-built PBX shifts the burden from continuous engineering to stable operation, helping teams prioritize clarity, control, and scalability as requirements grow.
