Maskbox is a Chrome extension: generate a throwaway email, paste it into any signup, and the verification code or link shows up right in the popup — one-tap copy, no inbox digging. No account, no real email. Asks for one permission.
Hey PH 👋 I'm the maker.
I built Maskbox because every "temp mail" I tried meant tab-switching to a
spammy junk inbox just to grab a 6-digit code. Maskbox surfaces the code (or
magic link) right in the toolbar popup — one tap to copy.
A few deliberate choices:
• Permanent address, not a 10-minute one — mail keeps arriving.
• Privacy by footprint: it asks for ONE permission (storage). No "read & change
data on all websites." You can verify that on the permission screen.
• No account, no password, no real email — ever.
Honest caveat: some sites block known disposable domains. It won't get you past
those, and I'd rather say that up front than collect 1-star "didn't work on X"
reviews.
It's free and solo-built. Would love feedback on the extraction accuracy and
which sites you'd want it to work on. AMA 🙏
