Project by qcodrr. This listing is based on source review, not a live mailbox test. Microsoft sign-in and an app registration are required.

After setup, keep it simple

python otp_reader.py
python otp_reader.py --watch
python otp_reader.py --from github

A reader, not a code generator.

The program looks for codes already sent to a mailbox you sign in to. It does not create accounts, receive SMS or skip a verification step.

Read before running

Follow the upstream repository for changes. Check the code and dependencies before granting account access.

Keep tokens private

Local token caches still contain sensitive access data. Leave them out of shared folders, support screenshots and commits.

Know the limits

Each guide covers the supported account types, requirements and common failure cases. A free download is not a guarantee of compatibility.
