Ubisoft 2-step verification and phone numbers: what to know

Updated 7 November 2026 · The ReserveSMS team

In short

  • Ubisoft’s 2-step verification uses an authenticator app or email, not texts.
  • Ubisoft may ask for a phone number for account recovery.
  • Rainbow Six Siege on PC needs 2-step verification on before you can play Ranked; save the backup codes.

Ubisoft protects accounts with 2-step verification, and some games need it turned on.

How it works

Ubisoft’s 2-step verification sends codes by email or uses an authenticator app. It may also ask for a phone number to help you recover the account.

Rainbow Six Siege

On PC, Rainbow Six Siege needs 2-step verification on before you can play Ranked.

Save your backup codes

Ubisoft gives you backup codes when you turn 2-step verification on. Keep them: you need them if you lose your authenticator. See backup and recovery codes.

Using a one-time number

A number from ReserveSMS receives codes for 20 minutes only, so it can’t help you recover the account later. Rely on the authenticator app and backup codes instead. Get a number for Ubisoft.
