Why an app asks for a verification code again later
In short
- Apps re-check you on a new device or from a new place, as Marktplaats does, or when activity looks unusual, as Vinted does.
- With two-step verification on, every sign-in can need a code: Amazon, X and others.
- A number you’ve stopped using can’t get those codes, so add an email or authenticator app.
Verifying a number once doesn’t mean the app won’t text it again. Many use the same number for later checks.
When apps ask again
- New device or place: Marktplaats texts a code when you log in on a new device or from somewhere different.
- Unusual activity: Vinted sends a code when it sees something odd, like a sign-in from a new device.
- Logging in: Wallapop and Glovo can text a code when you sign in.
- Two-step verification: Amazon and X can send a code at each sign-in once it’s on.
What it means for your number
The codes go to the number on the account. If that’s a number you no longer have, such as an old SIM or a one-time number, you can’t get them. A one-time number from ReserveSMS receives codes for 20 minutes only, so for accounts that ask again, switch to an email, an authenticator app, or a number you keep, straight after sign-up.
How to stay in
- Add an email you keep.
- Turn on an authenticator app where the app offers one. See text codes vs authenticator apps.
- Save backup codes. See backup and recovery codes.
Common questions
Why is the app asking for a code again?
Usually a new device, a new place, unusual activity or two-step verification. Apps such as Marktplaats and Vinted re-check you like this.
Can a one-time number receive later codes?
No. A ReserveSMS number receives codes for 20 minutes only, so switch the account to an email, an app or a number you keep.
How do I avoid being locked out?
Add an email you keep, an authenticator app and backup codes as soon as you’re in.
