Install Holehe on Linux in one command
Holehe asks about 120 services whether an email address is registered, using their password-reset and sign-up checks without sending anything to the address. It reports used, not used, or rate limited per site.
Holehe in three lines
pipx install otinstaller
ot install holehe
ot run holehe -- e:jane@example.comRuns megadose/holehe (GPL-3.0, ★ 15k, otinstaller v0.0.4, registry updated Oct 13, 2026). otinstaller installs and runs it; it does not change or verify it.
What Holehe is for
- Confirming an address is real and active before spending credits on it.
- Seeing which platforms to look at next for a given email.
- Bulk checks from a file with the original --only-used flag.
Typed inputs for Holehe
otinstaller translates these prefixes into Holehe's own flags. Anything else after -- is passed through unchanged, so every original flag still works.
- e:
- email ·
ot run holehe -- e:jane@example.com - u:
- username ·
ot run holehe -- u:jane_doe
Run every installed tool that takes the same input at once: ot run --all e:jane@example.com
Where the results go
Every run lands under ./results/holehe/<target>/ as a timestamped output file plus a .meta.json sidecar: the exact command, start and end time, exit code, and the SHA-256 of the output. Group runs with --case, compare the last two with ot diff holehe <target>, and pull indicators out with ot extract.
Before you run it
- Several services rate limit quickly; a rate-limited row is unknown, not absent.
- otinstaller runs Holehe with its password-recovery modules switched off by default.

When open-source isn't enough
Holehe says where an address is registered. SearchIn's leak and identity providers return the records behind it: breach rows, names, and linked accounts.
FAQ
Holehe with otinstaller, answered
How do I install Holehe on Kali or Ubuntu?
Install otinstaller once with pipx install otinstaller, run ot init, then ot install holehe. The tool lands in its own virtualenv under ~/.otinstaller/, pinned to a version that was tested on Ubuntu, so nothing touches your system Python. ot doctor flags a missing git or venv module.
Which inputs does Holehe take through otinstaller?
e: (email), u: (username). otinstaller maps each prefix to Holehe's own flag. Everything after -- that is not a typed input is passed through unchanged, so the original flags still work.
Where does otinstaller save Holehe results?
Under ./results/holehe/<target>/ in the folder you run from, as a timestamped output file plus a .meta.json sidecar with the exact command, timing, exit code, and SHA-256. Add --case <name> to group runs, and ot diff holehe <target> to compare the last two.
Does Holehe need an API key or a login?
No key is required for the basic run. Optional keys, where the project supports them, go in ~/.otinstaller/.env and are passed only to tools that declare them.
Can I run Holehe together with other tools?
Yes. ot run --all e:jane@example.com runs every installed tool that accepts email input, in parallel, including Holehe. Save the combination as a playbook to repeat it.
