Ubuntu 26.04 LTS Finally Ditches the Black Void: Sudo Now Shows Password Feedback

For over four decades, Linux users have faced the same unsettling experience when running commands with elevated privileges: a blank, unblinking terminal window staring back as they type their password. That era of silent uncertainty ends today with Ubuntu 26.04 LTS, which introduces visual feedback for sudo password entry—a change that’s already sparking passionate debates across the Linux community.

The Silent Treatment Ends

When you run a command with sudo in Ubuntu 26.04 LTS and enter your password, you’ll now see asterisks appear as you type—just like every other password field in modern computing. This seemingly simple change represents a significant departure from decades of tradition in the Linux world.

Previously, sudo would display nothing at all when you entered your password. No asterisks, no dots, not even a cursor movement—just an empty void that left users questioning whether their keyboard was even working. This behavior, inherited from the original sudo tool created in the 1980s, has been the source of confusion for countless newcomers to Linux.

Why Now? The Rust Revolution Behind the Change

Ubuntu’s switch to sudo-rs, a complete rewrite of the classic sudo tool in Rust, set the stage for this change. The transition happened quietly in Ubuntu 25.10, with most users unaware they were running different code under the hood. However, the visual feedback feature specifically arrived with Ubuntu 26.04 LTS.

Canonical developers cherry-picked a patch from the upstream sudo-rs project to enable password feedback by default. This decision reflects a broader philosophical shift about user experience versus theoretical security benefits.

The Security Debate That Won’t Die

The original design choice to hide password feedback was rooted in security concerns. The logic was straightforward: if someone could see your screen while you typed your password, they shouldn’t be able to count the number of characters you entered. This information could theoretically help an attacker narrow down possible passwords and make educated guesses.

However, the sudo-rs developers argue that this security benefit is “infinitesimal” in practice. Their reasoning is compelling: most users’ sudo passwords are identical to their login passwords, which are already visible to anyone watching them type at the login screen. Additionally, sophisticated attackers can often determine password length simply by listening to typing patterns.

The Community Reacts

As expected, the change hasn’t been universally welcomed. Someone filed a bug report with the dramatic title: “WHY?! This goes against DECADES of NOT ECHOING THE LENGTH OF THE PASSWORD TO SHOULDER SURFERS.” Ubuntu marked this bug as “Won’t Fix,” aligning with the upstream sudo-rs position that the change improves usability without meaningful security trade-offs.

The debate highlights a fundamental tension in security design: when does theoretical security benefit outweigh practical usability? In this case, the sudo-rs team decided that decades of user confusion represented a more significant problem than the hypothetical risk of shoulder surfing.

A Historical Perspective

What makes this change feel so radical is precisely how long the old behavior persisted. Since sudo’s creation in the 1980s, the blank password field has been a distinctive feature of Linux administration. Outside of sudo, no other password field on Linux systems omits feedback entirely.

This longevity created a situation where users had to learn a special, inconsistent behavior just for sudo commands. New Linux users, coming from Windows or macOS environments where password fields always provide visual feedback, often found themselves confused and frustrated.

How to Revert If You Must

For those who strongly prefer the traditional behavior, Ubuntu hasn’t removed the option. You can restore the blank password field by adding the line Defaults !pwfeedback to /etc/sudoers using the sudo visudo command. This will return you to the familiar silence that sudo has maintained for over 40 years.

What This Means for Linux Users

The change to password feedback in sudo represents more than just a cosmetic update. It’s part of a broader trend in Linux development toward improving user experience and reducing unnecessary barriers to entry. While hardcore users might dismiss such changes as “dumbing down” the system, they often make Linux more accessible to newcomers and reduce support burden.

The April 23, 2026 deadline mentioned in some discussions likely refers to when this behavior becomes standard across all Ubuntu releases, though the exact context remains unclear.

Final Thoughts

Whether you welcome the change or prefer the old way, sudo’s new password feedback marks an interesting moment in Linux history. It demonstrates how even long-standing conventions can evolve when developers re-examine their original assumptions in light of modern usage patterns and security realities.

As one commentator put it: “Finally, confirmation that my keyboard is actually working.” That simple reassurance, available in every other context, is now coming to sudo—and for many users, that’s worth celebrating.
