No more exchanging sensitive credentials over email or chat. By removing the need for password sharing, you reduce the risk of breaches and maintain a professional, secure process.
Gain access with precision. Leadsie gets you exactly the permissions you need—no more, no less. Avoid unnecessary admin access to client accounts, keeping your clients’ data safe and their trust intact.
With Leadsie you gain access as a partner business - so there's no need to set up accounts for clients that you own, or run campaigns through your own accounts. Clients can even create missing Meta assets like pixels, pages and ad accounts while they are granting access!
Simplify account access with a solution built specifically for agencies and MarTech platforms. With intuitive features, your onboarding won't just be more secure - you will spend less time gaining access and more time delivering results.
Leadsie uses encrypted tokens to automate the process of onboarding your clients or users. All data is encrypted both in transit and at rest, and can only be decrypted by the Leadsie app. Tokens expire based on platform rules (e.g. after 60 days with Meta), or with password changes - and they can be revoked at any time.


We host our platform in ISO 27001 and FISMA-certified data centres, adhering to the highest global security standards.
Leadsie is approved by Meta, Google, LinkedIn, TikTok and other integration partners, adhering to their strict standards. Our integrations are supported and monitored by these platforms.

For Facebook, you can get full manage or view-only access for pages, ad accounts and product catalogs. Leadsie can also give you indirect access to Pixels and Instagram accounts through your client's ad account, or full access with our advanced sharing feature. We give you access by adding you as a partner to your client's business manager. 
If your clients don't have a business manager or even an ad account, they can create it easily within Leadsie.
For Google, you can get manage or view-only access to Google Analytics, Google Ads (including Manager account / MCC support),  Tag Manager, Search Console, Business Profile and Merchant Center.
For TikTok, you can get view-only and manage access to TikTok Advertising accounts.

Yes! We have spent a lot of time making sure Leadsie is secure.
We are partnering with Meta, Google, TikTok (and more) and are approved for giving you access. When we grant your access to accounts, the required information (tokens) is encrypted and locked down to a database that only our Leadsie servers can access.
No one would be able to get access to you or your clients' accounts, even if our servers were compromised. We are also fully GDPR compliant and can provide a Data processing agreement (DPA) upon request.
No, they don't need to create an account with us. Your client only needs to log in with their Facebook, Google Account, LinkedIn and/or TikTok account.. Easy peasy! 😀
Of course not! Even if you cancel your subscription with us, you will still have access to your client - unless they decide to remove your access, of course.
