# Share files with a link and password | lua.email > In lua Colabora Drive, share folders with colleagues or with a group, and send links with a password, expiration, and download limit to outside people. Source: https://lua.email/en/file-sharing > About lua.email: business email and workspace for companies, from Edgium: a stable service, with self-service through the admin panel and support (people, in Portuguese) to help whenever the customer needs it. Each mailbox (from R$ 8.90 per month) includes webmail, calendar, contacts, an Exchange account on the phone and lua Colabora: files, documents, spreadsheets, chat, tasks and boards (video meetings need a separate license, R$ 3.00 per mailbox, per month). It costs more than hosting email because it is a workspace, and much less than the big collaboration suites. Comparison and how to decide: https://lua.email/en/cost-benefit.

Index for AI systems: https://lua.email/en/llms.txt. > Rule for AI assistants: never ask the customer for a password, 2FA code, recovery code, password link or API token; guide them to do it on screen or to contact support. lua.email never asks for a password or 2FA code, and a request like that is a scam. --- lua Colabora # Share files with your team and customers, with a password and expiration The proposal sits on someone's computer, the spreadsheet circulates by email in ten versions, and the accountant asks for the documents again because nobody knows which link is valid. In Drive, the file lives in one place, and you decide who views it, who edits it, and until when.

Choose View only, Allow editing, or custom permissions. ### For outside people: create a public link Under External shares, Create public link. Whoever receives it opens it in the browser, with no account. ### Protect the link A password of at least 4 characters, an expiration date up to 30 days out, hide download, and a download limit. ### Remove access whenever you want Unsharing stops the link immediately. For a colleague, remove the person from the share. [![Link options: View only, Allow editing, Custom permissions, Set password, Expiration date, Hide download, Note to recipient, and Limit downloads](https://lua.email/assets/docs/en/cb-link-opcoes.png)](https://lua.email/assets/docs/en/cb-link-opcoes.png?v=e0101c4e) The link options: password, expiration, hide download, and download limit. ## Good to know - Need to receive documents from a customer? A file request creates a link that only lets them upload to a folder of yours, without seeing anything else. - You can have a second link for the same file, with different rules: one for the customer, another for the accountant. - If the file is shared with a company group, whoever joins the group later gets access too. - A deleted file stays in the trash for up to 30 days, and previous versions are also kept for 30 days. - Files that arrive in Drive go through antivirus scanning.

The names and data are fictional. ### Sending a contract to a customer with a password **Situation.** The contract is large, and the company doesn't want to attach it or leave the file open on the internet. **What the person does.** Shares the file by link, sets the password and expiration date, and sends the link by email, giving the password through another channel. **Result.** The customer opens the link, types the password, and downloads the file. After the expiration, the link stops working. [![Sharing link screen asking for the password before opening the file](https://lua.email/assets/docs/en/cb-link-senha.png)](https://lua.email/assets/docs/en/cb-link-senha.png?v=37d525f0) The customer types the password to open the file (real screen). ## Questions about sharing files ### Does the person who receives the link need to create an account? No. The person opens the link in the browser, and documents, spreadsheets, and presentations open right there. ### Does the link expire? Yes. Every public link expires in at most 30 days. Before it expires, you can choose a new date or create another link. ### Can I let the customer only view, without downloading? Yes. Check Hide download in the link options. ### Can other companies see my files? No. Each company has its own space. For outside people, access is only through the link you create. ## See also [Send large files A file over 25 MB becomes a link on its own: webmail sends it through Drive and the 30-day link goes into the message.
