Frequently Asked Questions

What happens if I don't have my Synology recovery codes?
Without recovery codes, you'll need to contact Synology support for assistance. They may require proof of purchase and device ownership to help reset your account. This process can take several days.
Can I disable two-step verification permanently on my Synology NAS?
Yes, but it's not recommended for security reasons. After regaining access, you can disable 2FA in Control Panel > User & Group > User settings. However, keeping 2FA enabled with proper backup codes is much safer.
How many recovery codes does Synology provide?
Synology typically provides 10 recovery codes when you first set up two-step verification. Each code can only be used once, so keep track of which ones you've used and generate new codes when you're running low.
Will using a recovery code affect my data on the NAS?
No, using a recovery code to access your NAS will not affect your stored data. It only bypasses the two-step verification requirement for that login session. Your files, settings, and applications remain unchanged.
Can multiple users be locked out of 2FA at the same time?
Yes, if multiple users have 2FA enabled and lose their devices, each user will need their own recovery codes. Admin users can help reset 2FA for other users through the User & Group settings in Control Panel.
