I agree that phone-based sign-ups have become much more common lately. A lot of online services now try to make registration faster and easier, especially for people who mainly use their phones. Using a phone number can be convenient because it is simple, familiar, and often easier to recover than an account based only on email. At the same time, I’d still pay attention to privacy, security settings, and how the service handles personal information. Fast access is useful, but it shouldn’t come at the cost of clear rules and proper account protection.
