Can one authenticator app hold all your accounts?

A common worry when people start with 2FA: "Do I need a different app for each website?" Happily, no. One authenticator app can hold all of your accounts at once, and it keeps them tidy for you.

One app, many accounts

Every service that supports authenticator-app 2FA uses the same open standard, TOTP. Because the standard is universal, a single app can generate codes for Google, GitHub, Coinbase, Instagram, and hundreds more — all side by side.

How it stays organised

• Each account appears as its own labelled entry with the service name and usually your username.
• Each shows its own 6-digit code and a countdown timer.
• When you log in somewhere, you just find that service in the list and read its current code.

Add a new account any time by scanning its QR code — it slots in next to the others.

Is one app a single point of failure?

Only if you don't plan for it. Because everything lives in one place, make sure you can recover if the phone is lost:

• Save each service's backup codes.
• Consider a second device with the same accounts added.
• Know your lost-phone recovery options in advance.

The bottom line

One good authenticator app is all most people ever need. Add every account to it, back it up, and you've got strong 2FA across your whole digital life in one place. Browse setup guides →
