Signal 8.28: The Phone-Number-Free Signup Beta, Explained

Published: October 7, 2026 · Updated: October 8, 2026

What is new in Signal 8.28?

Signal 8.28.0's official release note is about one thing: you can now optionally register for Signal without a phone number. Signal calls it Signal Login, and it arrived as a beta test, with the notes asking users for help testing the new feature.

For years, a phone number was the one thing every Signal account needed. Usernames, which let you connect without sharing your number, already loosened that requirement. Numberless registration goes further: the number is no longer required at signup at all. It is optional, not the default. If you already have a Signal account, nothing about your registration changes.

Who is it for? Anyone who cannot or will not attach a phone number to a messaging account:

• people with a second device,
• people in places where getting a working number is hard, and
• anyone who simply wants the smallest possible link between their identity and their account.

For most users, the practical effect is zero. Registration looks the same as before, and the numberless path sits quietly to the side for the people who need it.

How numberless signup works

Signal's release notes describe the mechanics in plain terms. Phone-numberless registration requires a small one-time fee. The fee exists to make spam accounts expensive to create at scale. The in-app purchase is never directly associated with the new Signal account, which is the detail that matters: paying the fee does not create a link between your payment and your account.

A few honest caveats

• First, this is a beta. Beta features can change, break, or disappear, and the notes frame it as a test, not a finished product.
• Second, the fee is real money, small but nonzero, so it is worth knowing about before you go looking for the option.
• Third, everything else about Signal stays the same: end-to-end encryption, usernames, and the rest of the app work exactly as before.

The fee is a spam filter, not an identity check

The fee design is worth a second look, because it shows how Signal thinks about privacy tradeoffs. A signup fee could easily become a tracking link: pay with a card, and the account is tied to the card. Signal's notes explicitly rule that out, saying the purchase is never directly associated with the new account. The fee is a spam filter, not an identity check. That distinction is the whole reason the feature can exist without undermining the privacy it is meant to protect.

If you want to try features like this early, the Android beta guide explains how the beta channel works and what to expect from it.

The 8.28.x build line

Here is the 8.28 line as officially documented on GitHub:

The pattern is the usual one: one feature release, then a fast run of patches. The .1 patch landing the same day as the feature release is a good sign, not a bad one. It means testers found something quickly and Signal fixed it the same day.

A note on the media editor notes

Honest changelog journalism requires a detour here. If you open the GitHub pages for the 8.28.1 through 8.28.4 builds, you will find notes describing a redesigned media editor for tablets and foldables, with one-tap audio removal from videos. That is the same feature this site documents as the headline of the 8.29 release.

What happened? Signal's beta release notes sometimes describe features that are still in testing, and a feature can appear in one series' notes while it is being finished for the next. The media editor redesign was being tested during the late 8.28 builds and shipped as 8.29's headline change. This guide covers it in full on the 8.29 page, where it belongs, rather than double-counting it here.

The lesson for changelog readers: match the feature to the release whose notes announce it as new, and treat beta-build notes as a preview. The version numbering guide explains how to read Signal's tags so this kind of overlap does not confuse you.

Signal Login vs usernames: what is the difference?

Two different features solve two different problems, and 8.28's arrival makes it worth keeping them straight. Usernames let you connect with people without sharing your phone number. Someone can message you through your username and never see your number. But creating the account still required a number.

Signal Login, the 8.28 beta, attacks the other end of the same problem: the number is no longer required to create the account at all. Usernames hide your number from other people. Numberless registration removes the number from signup itself. Together, they cover both directions: who can see your number, and whether you need one to begin with.

In practice, most users will use one, the other, or neither, and that is fine. The features are independent. You can have a username on a number-registered account, a numberless account without a username, or both. Signal built them as separate options because they solve separate problems.

How to get 8.28

8.28 is behind the current stable build now, so most people will simply move past it to something newer. But the update paths are the same as always:

• Website build: the app checks for its own updates and offers them inside the app. Accept the offer and the newest build installs over your current one, chats intact.
• Play build: update through the Play Store like any other app.
• Manual route: download from Signal's official download page and install over your current website build. Same signature, so your data stays.

Before any update, make sure your backup is current. The Android backup guide shows the options, and the update walkthrough covers the manual path step by step.

8.28 in context

8.28 sits in the middle of Signal's busiest stretch of 2026. Earlier in the year, the version history shows 8.20 bringing linked Android phones and tablets with a better large-screen interface. Then 8.28 opened registration to people without phone numbers, and 8.29 rebuilt the media editor for the large screens 8.20 had started supporting. Read together, it is a clear direction: Signal spending the year making the app work for more devices, more screens, and more kinds of users.

The numberless signup is the most structural of the three changes. A new keyboard or editor changes how the app feels; a new registration path changes who can use it. That is why 8.28 matters even though its changelog is a single paragraph.
