Two-Factor Authentication for Gaming Accounts
Not all second factors are equal. SMS is the weakest and the one most games default to. Here is what to use instead.
The short answer
An authenticator app provides significantly stronger protection for gaming accounts than SMS-based two-factor authentication, because SMS codes can be intercepted through SIM swapping while app-generated codes cannot. Most gaming platforms including Steam, Roblox, Xbox, PlayStation and Epic support authenticator apps, and switching takes a few minutes per account. Recovery codes must be saved somewhere outside the phone that generates the codes.

The accounts people lose are rarely the ones with weak passwords. They are the ones with a strong password that also appeared in a data breach somewhere else.
A second factor makes that irrelevant. It is fifteen minutes of setup for the single largest security improvement available to a normal person.
SMS is the weakest option
A phone number can be moved to an attacker's SIM through carrier social engineering. Use SMS only where nothing better is offered.
The options ranked
Email codes have a hidden dependency worth naming: they are only as strong as the email account, so secure that first or the rest is theatre.
Step 1: Install an authenticator app
Pick one app for everything 3 minutes
Any standards-based authenticator works and they are interchangeable, since they all implement the same algorithm. Choose one that offers encrypted backup and confirm the backup is switched on after installation, because several do not enable it by default. One app holds every account and generates codes without a signal or data connection.
Step 2: Enable it on your highest-value accounts first
Email comes first because it is the reset path for everything else. An attacker with your email does not need your Steam password.
Steam is a special case: its authenticator is built into the Steam mobile app rather than a generic one, and enabling it imposes a hold on trades for a few days. That hold is a feature, not an obstacle.
Step 3: Save recovery codes outside the phone
Every service hands you recovery codes when you enable two-factor authentication. Most people close that screen without reading it.
Save them in a password manager, or print them and put them somewhere physical. Not in a note on the phone that generates the codes, which is the failure mode this step exists to prevent.
If an account is already compromised, the account recovery guide covers the order of operations, and enabling two-factor authentication is part of it rather than a substitute for it.

Frequently asked questions
Why is SMS considered weak?
Because a phone number can be transferred to an attacker's SIM through social engineering of a mobile carrier, a technique known as SIM swapping. Once the number moves, every SMS code goes to the attacker. It is still vastly better than no second factor at all, so use it where nothing else is offered, but move to an app wherever the option exists.
What happens if I lose my phone?
This is exactly what recovery codes are for. Each service gives you a set of one-time codes when you enable two-factor authentication, and any one of them logs you in without the app. Save them somewhere that is not the phone, such as a password manager or printed and stored physically. Without them, recovery means proving identity to support, which is slow and sometimes fails.
Does two-factor authentication stop phishing?
It raises the bar substantially but does not eliminate the risk, because a convincing fake login page can ask for the code as well as the password and relay both in real time. The defence against that is never signing in from a link. Two-factor authentication protects you from password reuse and database leaks, which are the more common threats.
Should I use my email provider's authenticator?
Any standards-based authenticator app works, and they are interchangeable because they all implement the same algorithm. What matters more is choosing one that offers an encrypted backup, so a lost phone does not mean re-enrolling every account. Check that backups are enabled after installing, because several apps do not enable them by default.
