Fluxer sends you an email to verify your address, to approve a sign-in from a new IP address or to reset your password. If one of these emails doesn't arrive or none of the answers below help, you can [contact our support team](https://fluxer.com/help/contact.md), and a person on our team will help you. ## Why do I keep getting emails about a sign-in from a new IP address? When you sign in with your password from an IP address your account hasn't approved before, and your account doesn't use two-factor authentication, [we email you](https://fluxer.com/help/new-ip-sign-in-email.md) before you're signed in. Mobile networks, VPNs and some home connections change your IP address often, and you can get a new email each time it changes. ## Why does the new IP link send me back to the sign-in screen? The sign-in screen that sent the email keeps waiting, and it signs you in by itself once you open the link, even if you open it on another device. If you closed that sign-in screen first, [sign in again from the same network](https://fluxer.com/help/new-ip-sign-in-email.md) and ask for a new email. ## Why didn't my verification or password reset email arrive? Check your spam folder and your [inbox rules](https://fluxer.com/help/verification-email-not-arriving.md), then ask for a new email from the sign-in screen. If it still doesn't arrive, email support@fluxer.com from the address on your account, and a person on our team will help you get signed in again. ## Why is the sign-up check slow? The sign-up form has a captcha that your device solves by itself in the background. There's no puzzle to click, and we don't use an outside captcha service. It takes longer on slower devices and when many people sign up at once, and it needs JavaScript and HTTPS. ## Why does Fluxer say my network is blocked? Fluxer can block a network address because of activity on it that broke our rules, and many people can share one address, for example on a VPN or at a school. If you think it's a mistake, write to the address in the message, and a person on our team will look at it. ## How do I change my email if I can't get into my old inbox? If your old mailbox was deleted and email to it can't be delivered, you can replace the address using only a code sent to the new one. If the mailbox still exists but [you can't get into it](https://fluxer.com/help/verification-email-not-arriving.md), email support@fluxer.com, and a person on our team will look into it. ## Can I sign in to Fluxer with a QR code? No. Fluxer doesn't have sign-in with a QR code, and it isn't one of the items on our [Roadmap 2026](https://fluxer.com/blog/roadmap-2026.md). If you'd like to see it added, you can suggest it on [Fluxer Feedback](https://feedback.fluxer.com). The desktop app can sign you in through your browser. To use a browser on another device, click "Signing in on another device?", sign in there and type in the code the app shows. ## I started Fluxer with only a name An account you started with only a name works only on the device where you made it. To use it anywhere else, [add an email to it](https://fluxer.com/help/claim-account.md) first, and then you can sign in on any device. ## Is a prompt to confirm my password a lock? No. Before a sensitive change, such as deleting your account, Fluxer asks you to confirm it's you with your password, [two-factor authentication](https://fluxer.com/help/two-factor.md), a passkey or an emailed code. Your account isn't locked, and the change goes through once you confirm. --- Canonical page: https://fluxer.com/help/sign-in-problems Last updated on November 1, 2026
