Family Shared Cloud Storage: A Practical Guide
Most "family" cloud plans actually mean one login, one password, and everyone's files sitting in the same account. Here's how a proper family setup should work — one plan, separate logins, and nobody able to read anyone else's files but their own.
The problem with sharing a single account
The easiest way to "share" cloud storage with a partner, kids, or parents is to hand them the same email and password. It works, technically. It also means:
- Everyone sees everyone's files — there's no separation between your tax documents and your teenager's homework folder.
- One person's mistake (a phishing link, a reused password from a breach elsewhere) locks out the whole family.
- You can't remove access for one person without changing the password for all of them.
- There's no way to tell who uploaded, deleted, or moved a given file.
None of this is a hypothetical edge case — it's the default outcome of "just share the login," and it's why real family plans give each person their own account instead.
How Apple, Google and Microsoft actually do it
The mainstream providers already solved the login problem correctly: each family member keeps their own Apple ID, Google account, or Microsoft account, and one "organizer" pays for a plan that pools the storage quota across everyone. Nobody shares a password, and each person's files stay under their own account.
What none of those setups change is who can read the files. Apple, Google, and Microsoft all hold the encryption keys for the data in your account — meaning the provider (and by extension, anyone who compromises the provider, or is legally compelled to comply with a data request) can technically access every family member's files, not just the organizer's own data. Pooling the quota solves the login problem. It doesn't solve the privacy one.
How family sharing works on LifetimeCloud
LifetimeCloud's family sharing is built around the same principle — separate accounts, pooled storage — with one difference: encryption keys are derived from each person's own password, in their own browser, and never leave their device. The plan owner can't read a member's files any more than the provider can.
| Step | What happens |
|---|---|
| 1. Owner sends an invite | From account settings, the plan owner enters a family member's email. An invite link is emailed to them, valid for 7 days. |
| 2. Member accepts | They create their own account and password — nothing is shared with the owner or with anyone else's login. |
| 3. Member gets their own vault | Their password derives their own AES-256 encryption key locally. The owner, LifetimeCloud, and every other family member are locked out of it by design. |
| 4. Storage is pooled, not split | All members draw from the owner's plan quota — there's no fixed per-person allocation that goes to waste if one person uses less. |
A member can leave the family at any time from their own account, and the owner can remove a member at any time — either way, that person simply reverts to their own free-tier quota. Nothing about their existing files or encryption changes; they just stop drawing from the shared pool.
Working out how much storage a family actually needs
Before picking a plan, it helps to estimate combined usage rather than gut-feeling it. Rough per-person ranges, assuming phone photos/videos plus some documents and no professional video work:
- Light user (mostly documents, occasional photos): 20–60 GB
- Typical smartphone user (regular photos, some 4K video clips): 80–200 GB
- Heavy media user (lots of 4K/HDR video, large photo libraries): 250 GB+
A household of two adults and two kids with typical phone usage lands somewhere around 300–500 GB combined, comfortably inside a 1 TB plan with headroom to grow. A household that also backs up drone or camera footage should size up to 2 TB.
Plans and member limits
| Plan | Storage | Family members | Current price |
|---|---|---|---|
| 1 TB | 1024 GB pooled | Up to 3 | €49 one-time |
| 2 TB | 2048 GB pooled | Up to 5 | €79 one-time |
Both prices are one-time payments, not recurring charges — check the pricing section for the current numbers, since introductory pricing changes over time.
Setting it up
- The plan owner opens their account settings and finds the family section.
- They enter each family member's email address — one invite per person, up to the plan's member limit.
- Each invitee clicks the link in their email, sets their own password, and their vault is created automatically, encrypted with a key only they hold.
- The owner's dashboard shows combined usage across all members, so it's easy to see when the family is approaching the plan's quota.
Two things worth knowing going in: a member can only belong to one family at a time, and someone who already has their own family members set up under their account can't also join someone else's — you can be an owner or a member, not both.
What to check before sharing storage with anyone
If you're evaluating whether a family plan actually protects everyone's privacy, three questions cut through the marketing:
- Does each person get their own password and encryption key, or just their own folder inside one shared account? A folder isn't a security boundary — the storage location is not the security boundary, encryption key ownership is.
- Can the plan owner read other members' files? If yes, "private" storage isn't actually private from your own family, let alone the provider.
- What happens when someone leaves? Removing a member should immediately end their access to the pool without touching their existing encrypted files.
One plan. Separate vaults. Nobody in between.
LifetimeCloud's family sharing pools storage across up to 5 accounts while keeping every member's encryption key their own — including the plan owner's.
