Today is the day that Azure Storage stops supporting Transport Layer Security (TLS) versions 1.0 and 1.1. TLS 1.2 is the new minimum.
The change has been long overdue. Microsoft warned users several years ago that February 3, 2026 would be the end date after which the deprecated standards would no longer be supported.
The minimum TLS version will be enforced at the storage account level. Microsoft stated:
“If your storage account hosts other Azure Storage services (such as Azure Files, Queue Storage, or Table Storage), those services are also subject to the same TLS requirements.”
TLS is a security protocol for encrypted communications between applications and servers. In this case, when accessing stored data over HTTPS, the communications are encrypted using the TLS protocol.
The deprecated standards, TLS 1.0 and 1.1, come from a different era of computing. TLS 1.0 dates back to 1999, and version 1.1 was released in 2006. Both versions were deprecated in 2021, years after the TLS 1.2 standard was released in 2008. The latest protocol, TLS 1.3, was released in 2018.
Microsoft kept TLS 1.0 and 1.1 versions obsolete, mainly for compatibility with older software versions. Windows 7, for example, supported older versions by default and required manual modifications to enable TLS 1.2.
Microsoft has been trying to retire TLS 1.0 and 1.1 and earlier. It originally set a November 1, 2024 deadline, but it was pushed back a year to November 1, 2025. Administrators and developers of legacy applications were given a little more time, until February 3, 2026.
The company has not stated that it will grant an additional extension to the deadline.
Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
