Passkeys Are Winning in 2026 — But These App Categories Still Force SMS OTP on You

# Passkeys Are Winning in 2026 — But These App Categories Still Force SMS OTP on You

**Passkeys** are having their mainstream moment in 2026. Apple, Google, and Microsoft have all shipped passkey support across their platforms, and major services are actively migrating users away from passwords.

The security improvement is real: passkeys use public-key cryptography to authenticate users without transmitting secrets. There's no password to phish, no SMS code to intercept.

But here's the reality check: **the passkey transition will take years, not months.** Thousands of apps — especially in crypto, gaming, gig economy, and AI — still require SMS OTP verification to create an account.

This guide covers which app categories still depend on SMS OTP in 2026, why they're slower to change, and how using a **secondary virtual number** protects your real phone number in the meantime.

## Where Passkeys Have Won (And Where They Haven't)

**Already passkey-first in 2026:** - Google, Apple, Microsoft accounts - Major banking apps (Chase, Bank of America, Wells Fargo) - Password managers (1Password, Bitwarden) - GitHub and select developer platforms

**Still relying on SMS OTP for initial verification:** - Crypto exchanges - Fintech apps and neobanks - Gig economy platforms - Gaming and streaming services - AI tools and chatbots - Online marketplaces - International apps (Southeast Asia, South Asia, Latin America)

The pattern is clear: **established, regulated platforms** have moved toward passkeys. **Newer, growth-stage apps** still lean on SMS OTP because it's cheap to implement, globally accessible, and familiar to users.

## 7 App Categories Still Running on SMS OTP in 2026

### 1. Crypto Exchanges and Web3 Platforms

Crypto platforms have unique reasons to stick with SMS verification: global user bases, regulatory KYC requirements, and the need to verify "one person, one account" at scale. Despite the irony of using a vulnerable channel to protect high-value assets, SMS OTP remains the verification baseline for most exchanges.

**Risk level: Highest.** Crypto accounts are a top SIM swap target. Never use your real number here.

### 2. Fintech Apps and Neobanks

New financial apps — digital wallets, BNPL services, expense trackers — often launch with SMS OTP as their primary verification. Regulatory compliance requirements around phone-based identity verification have been slow to update alongside passkey standards.

**Risk level: High.** Financial data and potential payment access make these accounts valuable to attackers.

### 3. Gig Economy Platforms

Uber, DoorDash, Fiverr, Upwork, TaskRabbit — virtually all gig platforms require phone OTP verification. They use it to enforce one-account-per-person policies and facilitate payment. Passkey adoption here is minimal as of mid-2026.

**Risk level: Medium-high.** Your real number becomes your identifier across the platform and can be exposed to gig clients.

### 4. Online Marketplaces

eBay, Etsy, Facebook Marketplace, and international equivalents use phone verification to build trust between buyers and sellers. Passkey support is either absent or optional.

**Risk level: Medium.** Marketplace accounts with payment methods are targeted for account takeover and fraud.

### 5. Gaming and Streaming Platforms

Game launchers, mobile gaming platforms, and streaming services still gate account creation behind SMS verification to prevent multi-account abuse. The category has been particularly slow to adopt passkeys.

**Risk level: Medium.** Gaming accounts with in-game currency or payment methods have real monetary value.

### 6. AI Tools and Chatbots

The entire AI app category runs on SMS OTP verification as of 2026 — partly because the apps are new and passkey infrastructure requires investment, partly because phone verification is the simplest way to limit bot signups. AI data breaches surged 40% this year, making this category especially risky.

**Risk level: Medium-high** given the sector's breach rate.

### 7. International Apps Targeting Emerging Markets

Apps primarily targeting users in Southeast Asia, India, Latin America, and sub-Saharan Africa overwhelmingly use SMS OTP because smartphone penetration runs ahead of passkey-compatible hardware and OS versions.

**Risk level: Variable.**

## Why Passkeys Won't Eliminate the OTP Problem Entirely

Even as passkeys proliferate, SMS OTP will persist for two structural reasons:

**Account recovery.** Even on passkey-first platforms, SMS OTP is often the backup recovery method. If you lose your passkey device, the platform falls back to sending a code to your registered phone number. Your real number remains a vector even on passkey-enabled services.

**Initial account creation.** Many platforms that accept passkeys for login still require SMS verification for the initial signup — a "prove you're human and have a real phone" gate. Your number is logged even if passkeys take over for login.

## The Secondary Number Strategy for 2026

The practical approach: **use a secondary virtual number for every SMS OTP verification on platforms that haven't yet adopted passkeys.**

[OTPStream](https://otpstream.com) covers all the major services in the categories above — crypto exchanges, fintech apps, gig platforms, marketplaces, and AI tools. The workflow:

1. When a new app asks for phone verification, open [OTPStream](https://otpstream.com/dashboard) 2. Create a new order for that specific service 3. Enter the virtual number in the app 4. Receive the OTP in your OTPStream dashboard and enter it 5. Done — the app has a number, your real mobile was never involved

As these platforms eventually migrate to passkeys, the account continues working normally. If the platform has a breach in the meantime, the exposed number is a virtual one with no downstream attack value.

## The Bottom Line

Passkeys represent the right long-term direction for authentication. The security industry's move away from SMS OTP is correct.

But in 2026, you can't wait for every app to catch up. Crypto exchanges, gig platforms, AI tools, and international apps will be on SMS OTP for years. Every one of those verifications is an opportunity to protect your real number or expose it.
