Is Skype Safe to Use in 2026?
Skype, now a Microsoft product, has a complicated privacy history. The platform was revealed to have participated in the NSA PRISM surveillance program, and Microsoft contractors were caught listening to Skype calls for quality improvement. While Skype has introduced end-to-end encryption for private conversations, standard calls and messages are not encrypted end-to-end by default. Skype data feeds into the Microsoft ecosystem alongside Teams, Outlook, and Bing. With Microsoft increasingly directing users toward Teams, Skype receives less development attention and security investment. Skype earns a caution rating for its surveillance history, inconsistent encryption, and declining platform priority within Microsoft.
What Skype Collects
- Call and message metadata including contacts, timestamps, duration, and usage patterns across the platform
- Message content for standard conversations that are not protected by Private Conversations end-to-end encryption
- Device information, IP addresses, Microsoft account data, and usage analytics integrated with Microsoft ecosystem
- Voice data that was historically collected for quality improvement, with contractors listening to call samples
Who Sees Your Data
- Microsoft Corporation which processes Skype data as part of its broader communications and cloud services portfolio
- Intelligence agencies, as Skype was confirmed as part of the NSA PRISM surveillance program before and after Microsoft acquisition
- Microsoft contractors who have historically been given access to Skype call recordings for quality improvement purposes
PRISM and Surveillance History
Skype was identified as a participant in the NSA PRISM surveillance program in documents leaked by Edward Snowden. The program allowed intelligence agencies to access communications data from major technology companies. Skype participation meant that calls, messages, and video chats were accessible to government surveillance. This access existed both before and after Microsoft acquisition of Skype. While the legal landscape around government surveillance has evolved since the Snowden revelations, the confirmed participation in mass surveillance programs represents a fundamental breach of user trust. The technical infrastructure that enabled this access may have been modified but the willingness to cooperate with mass surveillance remains a relevant consideration for Skype privacy assessment.
Human Review of Calls
In 2019, it was revealed that Microsoft contractors were listening to Skype calls and Cortana voice commands as part of a quality improvement program. Users were not informed that their conversations were being reviewed by human workers. The workers heard personal conversations, intimate moments, and sensitive discussions. Microsoft subsequently updated its privacy policy and provided more transparent controls, but the incident demonstrated that Skype calls were not only accessible to Microsoft systems but were actively being listened to by contractors. This human review program operated for years before public disclosure, raising questions about what other undisclosed data access practices may exist.
Declining Platform Investment
Microsoft has increasingly shifted focus to Teams as its primary communication platform, which means Skype receives less development attention, security updates, and engineering resources. A platform with declining investment is more likely to have unpatched security vulnerabilities and slower response to emerging threats. Users who rely on Skype for sensitive communications should consider whether a platform in maintenance mode is appropriate for their needs. The reduced engineering attention also means fewer privacy improvements and slower adoption of modern security standards. For users still on Skype, migrating to a more actively developed and security-focused platform is a prudent choice.
Recommended Privacy Settings
| Setting | Where | Recommended |
|---|---|---|
| Private Conversations | Chat > New Private Conversation | Use Private Conversations feature for sensitive messages to enable end-to-end encryption that standard chats lack |
| Profile Visibility | Settings > Account > Profile | Limit profile visibility and minimize personal information shared on your Skype profile |
| Voice Data Collection | Microsoft Privacy Settings > Voice | Opt out of voice data collection through Microsoft privacy dashboard to prevent call audio from being reviewed |
Safer Alternatives
End-to-end encrypted calls and messages by default with no surveillance history and no corporate data collection
Open-source video conferencing with no account required and no history of participation in surveillance programs
Our Verdict
Skype earns a caution rating based on its confirmed participation in NSA surveillance, the human review of user calls by contractors, inconsistent encryption that requires manual activation, and declining development investment from Microsoft. The platform history of privacy failures is more severe than most messaging alternatives, and the shift of Microsoft resources toward Teams means Skype security posture is unlikely to improve. Users should migrate to platforms with stronger privacy foundations. Signal provides end-to-end encryption by default with no surveillance history, making it the recommended replacement for anyone currently relying on Skype for private communication.

Frequently Asked Questions
Was Skype really part of the NSA surveillance program?
Yes, Skype was confirmed as a participant in the NSA PRISM program through documents leaked by Edward Snowden in 2013. The documents showed that the NSA had access to Skype communications including voice calls, video calls, file transfers, and text messages. This access existed before Microsoft acquired Skype and continued afterward. Microsoft has stated that it only provides data in response to valid legal requests, but the PRISM program represented a broader access arrangement. While the legal framework has been updated since then, the confirmed participation in mass surveillance is a historical fact that remains relevant to assessing Skype trustworthiness for private communication.
Are Skype calls encrypted end-to-end?
Standard Skype calls and messages are not end-to-end encrypted. They use transport encryption that protects data during transmission but allows Microsoft servers to access the content. Skype offers a Private Conversations feature that provides end-to-end encryption using the Signal Protocol, but it must be manually initiated for each conversation. Most Skype users do not use Private Conversations and therefore their communications are accessible to Microsoft. For calls where privacy matters, either use the Private Conversations feature specifically or switch to a platform like Signal that encrypts everything by default without requiring manual activation.
Should I switch from Skype to another platform?
Given Skype declining development priority at Microsoft, its surveillance history, and the availability of better alternatives, switching is generally advisable. For personal communication, Signal provides superior encryption and privacy. For workplace communication, your organization likely prefers Teams or another enterprise platform. For video conferencing with non-contacts, Jitsi Meet is open source and requires no account. Skype main remaining advantage is its large installed base, but as Microsoft migrates users to Teams and the platform receives less security attention, the reasons to stay on Skype diminish while the reasons to leave strengthen.
