Turn off

Open Account → Security and click Disable next to Two-factor authentication (TOTP).
Click Send verification code.
Enter the code from your email and the code from your authenticator app, then click Disable 2FA.

After that, withdrawals are blocked for 24 hours, and you are logged out on your other devices. You get a notification and an email.

Move to a new phone or app

If you saved the key when you turned 2FA on, you can simply add it to the new app. Nothing changes in your Strade account.

To get a new key, change the app while you still have the old one:

Open Account → Security and click Change next to Two-factor authentication (TOTP).
Scan the new QR code with the new app (or enter the key manually) and save the key in a safe place. Click Next: only then we send a code to your email.
Enter the Code from the new app, the Code from the current app and the code from your email, then click Verify & change.

Until you confirm, the old app keeps working. After the change, only codes from the new app work, withdrawals are blocked for 24 hours, and you are logged out on your other devices. You get a notification and an email.

If you no longer have the old app, see I lost access to my authenticator app.

Why withdrawals are blocked: Why are my withdrawals blocked for 24 hours?

Stay safe: Strade support never asks for your password, 2FA codes or seed phrase. We recommend keeping 2FA on.
