Want to post anonymously on Facebook but can't find the option? Anonymous participation requires an eligible group with the feature enabled. Start with your posting identity, then check the audience before sharing anything private.
Choose anonymous authorship for your group post
Anonymous posting is available in eligible Facebook groups with anonymous participation enabled. Check that requirement before writing something you intend to share anonymously.
Start a post in the group where you want to share.
Toggle on Post anonymously before publishing, then confirm with Got it.
Write your post, leaving out your name and other identifying details you don't want to share.
Publish only after checking your chosen posting identity.
Members can choose anonymous authorship in groups where anonymous participation is enabled, and not every group enables it.
On a computer, go to facebook.com/groups, select your group, click Write something..., click the toggle next to Post anonymously, click Got it, then create your post and click Submit. In the mobile apps, tap Write something..., tap your profile name, toggle Post anonymously, tap Got it, then tap Post.
Check the group if anonymous posting is missing
A group without anonymous participation enabled does not support anonymous posting.
Check whether the group offers anonymous participation.
If you cannot choose anonymous authorship, hold off on publishing anything you intended to share anonymously.
Meta publishes instructions for desktop, Android, iPhone, iPad, mobile browsers, and Facebook Lite, so the feature isn't tied to one platform. Switching devices still won't help when the option is missing, because eligibility depends on the group rather than on what you're using.
Meta states you can participate anonymously only if anonymous participation is available to your group, the group admins allow it, and it's available to you. Browser incognito mode, a VPN, and account privacy settings change none of those three conditions, so none of them unlocks anonymous posting in a group that doesn't offer it.
Group admins control the feature. In Group settings, under Manage discussion, they use Edit next to Anonymous participation to turn it on or off. Admins can also require anonymous and nickname posts and post edits to be approved by admins or moderators, even if post approval isn't turned on for the group, so your contribution may wait for review before it appears. A missing option means the group hasn't enabled the feature, not that Facebook has removed it.
Use a nickname instead
Groups offering nicknames within anonymous participation let you use one for posts and comments.
Start a post in a group that offers nicknames.
Choose a nickname as the identity for your contribution.
Write your post.
Publish using that nickname.
A nickname is another supported authorship choice where the group offers it within anonymous participation. Meta confirms its use for both posts and comments, so the option is not limited to starting a discussion.
If you don't see a nickname choice, that option isn't available to you in this group.
To set one, open the composer, toggle on Post anonymously, then choose Customize a nickname, enter the nickname you want, and tap Save. A green checkmark means it's available; two people can't use the same nickname at the same time, and you can only change your nickname once every 2 days. To switch identities, tap Post as [your nickname]… and toggle off Post anonymously, or choose Post anonymously without a nickname. Meta documents no custom avatar picker for nicknames, and you can't use Live Video, share content, or send messages under one. Additional profiles and Pages are separate features with their own group rules, and Meta doesn't present either one as a substitute for anonymous participation.
Choose anonymous authorship for comments too
Anonymous participation also includes comments in groups with the feature enabled. You don't have to start a new post to participate anonymously.
Choose anonymous authorship for the comment you want to contribute.
For a comment under a nickname, choose a nickname in a group that offers that option.
Meta's current instructions give the comment workflow directly: go to the group post, tap Comment, tap your profile picture next to Write a comment…, then select anonymous member in a private group or anonymous participant in a public group and follow the prompts. To go back, tap your profile picture again and select your main profile.
That identity picker is exactly what you use on someone else's post: open their post, tap Comment, and choose your anonymous identity before you start writing.
Anonymous reactions are supported wherever anonymous participation is enabled, subject to group and account availability. Tap your profile picture next to Write a comment…, select anonymous member in a private group or anonymous participant in a public group, then select the reaction. Admins enable posting, commenting and reacting together, so a group can't allow anonymous posts but not anonymous comments.
Review the audience before sharing
Posting in a public group? Meta says new public-group content can be visible to anyone, including people without Facebook accounts. Anonymous authorship does not make the content private.
Review your post for details you don't want a public audience to see.
Remove sensitive information you don't want shared publicly before publishing, whether you use anonymous authorship or a nickname.
A nickname changes the authorship choice for your contribution; it does not establish a restricted audience. The public visibility of new public-group content still matters when deciding what to include.
Apply the same audience check to comments. Anonymous commenting is a supported feature, but choosing anonymous authorship does not turn public-group content into a private exchange.
One limit matters most here: anonymity applies to other members, not to everyone. Meta states that if you participate anonymously, your name and profile photo are still visible to admins, moderators and Facebook's systems. Your contribution shows as Anonymous member in private groups or Anonymous participant in public groups.
