Signal has started rolling out Signal Login, an optional registration method that allows users to create a Signal account without providing a phone number. The feature will be rolled out first on Android and will come to iOS later.
As we previously reported, Signal Login is not a free alternative registration method. Signal requires users who choose to register without a phone number to make a one-time payment. The price at launch is $2.99 / € 3.49, although this may vary by region and currency.
Interesting how Deltachat and Jabber, both decentralized encrypted messaging apps (as opposed to Signal, which is centralized), don’t even require an email to create an account, let alone a phone number or payment.
