The short version

  • Each has a real cost: Bitwarden the integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month; Microsoft OneNote notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • They diverge on capability: Bitwarden covers Unlimited password storage, Microsoft OneNote covers Free-form page canvas.
  • Prices and features above were last checked on 30 August 2026.

Microsoft OneNote

  • Handwritten notes on a pen tablet that you still need to find months later by searching for a word you wrote.not Bitwarden
  • Lecture or meeting notes where a recording needs to line up with what you were typing at the time.not Bitwarden
  • A team already inside Microsoft 365 that needs a shared notebook without buying anything or seeking approval.not Bitwarden
  • Collecting mixed material such as screenshots, clippings and sketches on one page, where a document editor would force a linear structure.not Bitwarden

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bitwarden

  • The integrated TOTP authenticator, encrypted file attachments, vault health reports and Emergency Access are all withheld from the free plan and need Premium at $1.65 per month
  • Free accounts can share vault items with one other Bitwarden user and no more
  • File storage is capped at 5 GB on Premium and 5 GB personal plus 5 GB family on the Families plan
  • Two-step login accepts up to 10 hardware security keys per account
  • The Families plan is capped at 6 people, so a seventh member means moving to a Teams subscription at $4 per user per month

Microsoft OneNote

  • Notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • Personal notebooks consume OneDrive quota, which is 5 GB on a free Microsoft account, so a notebook full of scans, images and recordings quietly exhausts the whole account including the space Outlook needs for mail.
  • Sync happens at section level and conflicts are resolved by placing both versions on the page, so simultaneous edits to a large or media-heavy section produce duplicated content that somebody has to merge by hand.
  • Search behaves differently across clients, so what the Windows desktop app finds inside handwriting, images and attachments is not necessarily what the browser or mobile version finds, and the same query gives different answers on different devices.
  • There is no relational structure, no database and no properties, so anything that needs a table of records with fields has to be maintained by hand or moved elsewhere, and OneNote's own tables cannot be queried or filtered.

Answered from the vendors’ own pages

Bitwarden: Does Bitwarden have a free plan?

Yes, Bitwarden offers a free tier with basic password management, zero-knowledge encryption, advanced two-step login, and unlimited devices across browser, mobile, and desktop apps.

Source
Microsoft OneNote: Is OneNote really free?

Yes. The application is free with a Microsoft account, with no time limit and no feature gate. What you may end up paying for is the OneDrive storage the notebooks consume.

Bitwarden: How much does Bitwarden Premium cost?

Bitwarden Premium costs $1.65 per month billed annually at $19.80 per year, including integrated authenticator, file attachments, emergency access, and security reports.

Source
Microsoft OneNote: Can I keep notebooks off Microsoft's cloud?

The Windows desktop app can keep local notebooks, but they will not sync to other devices and any shared access requires OneDrive or SharePoint.

Bitwarden: What is the difference between Bitwarden Teams and Enterprise?

Teams plan at $4 per user per month (annual billing) includes centralized ownership and secure credential sharing. Enterprise at $6 per user per month adds granular access control, passwordless SSO, account recovery, self-hosting, and complimentary Families plans for all users.

Source
Microsoft OneNote: How do I get my notes out?

Section by section as a OneNote file, a PDF or a Word document. A OneNote package preserves a whole notebook but only for another copy of OneNote. Third-party converters exist and the page layout usually does not survive them.

Microsoft OneNote: Which version should I install?

Microsoft consolidated onto a single OneNote application on Windows after retiring the Store version, so install the one distributed with Microsoft 365 rather than looking for an alternative.
