@Germain -

No, you can use the Visitor access method (https://help.miro.com/hc/en-us/articles/360012524559-Collaboration-with-visitors) or the beta Guest access method (https://help.miro.com/hc/en-us/articles/360021415119-Collaboration-with-guests) to provide folks with edit access to your board without having them become Miro users first. The latter is only available on Consultant, Business & Enterprise plans at present, whereas the former is available on all paid plans.

@Germain - I’m not sure if you made any changes to your board’s permissions since you originally posted, but as @Kiron Bondale  has outlined, yes, you can set your board so that anyone on the internet can see it, e.g., if you open this post in an Incognito/private browser windows, your board is visible.

Anyone Miro board in any plan type can be set to be publicly viewable, with the except of the Enterprise Plan, only if admin has disabled this functionality in the Enterprise Plan Sharing policies.
