When Should You Use a One-Time PIN Instead of a Lockin Guest PIN?

If someone needs to unlock your Lockin Veno Solar Palm once, for a short, specific visit, use a one-time PIN. If the person needs repeat access or access across a defined stay or schedule, use the corresponding guest-password type instead: periodic for recurring visits or duration for a time-bounded stay.

The important distinction is not the word “guest.” On the Veno Solar Palm, one-time, periodic, and duration passwords are all ways to share temporary access, but they have different expiry rules and entry behavior. A one-time PIN is for a single use; it is not the best fit for a cleaner who visits every week or a guest staying for several days.

One-time PIN vs. Lockin guest PIN: the quick decision

Use this decision table for the Veno Solar Palm. Lockin’s product page describes one-time, scheduled, and recurring passcodes for guests and service visitors; the detailed conditions below come from the current Veno Solar Palm/Veno Solar Face user manual. For another Lockin model, check its matching manual before assuming the same rules apply.

Visit pattern Better choice Why
A delivery, friend, or contractor needs one entry One-time password It is designed for temporary guests, remains valid for one hour, and expires after first use.
A cleaner or dog walker visits on selected days Periodic password You can assign recurring active hours, and the password expires when the schedule ends.
A visitor needs access during a defined stay, such as a rental or house-sitting period Duration password It is set for a time-bounded visit and auto-expires when the stay ends.
A family member needs ongoing personal access A managed user PIN or biometric access Do not use a one-time credential for a continuing household role. Follow the model’s access-management instructions.

When a one-time PIN is the right fit

Choose a one-time PIN when all three conditions are true:

  1. The visit is singular. The person should unlock the door once, not return on a repeating schedule.
  2. The access window is short. On the Veno Solar Palm, the manual describes a one-hour validity period.
  3. The credential should end after use. The manual says the password expires after the first use.

That makes a one-time PIN a practical choice for a one-off repair visit, a friend arriving while you are away, or a delivery that requires entry. It also avoids leaving a reusable guest credential active after the visit.

The manual also says that a generated one-time password cannot be retrieved later and that it can remain valid while the lock is offline after generation. Copy it when you create it, share it privately, and confirm that the recipient has the complete code before they arrive. Never publish an active PIN in a group chat or public post.

When a recurring or duration guest PIN is better

A one-time PIN becomes the wrong tool when the access pattern is predictable or lasts beyond one visit.

Choose a periodic PIN for repeating visits

Use a periodic password for a cleaner, dog walker, caregiver, or similar visitor who needs access on a recurring schedule. The Solar Palm manual gives an example of selected weekdays and active hours. The schedule limits when the credential is usable, so you do not have to send a new one-time PIN for every visit.

The manual says periodic passwords support the anti-peep feature. That means extra digits may be entered before or after the real password, subject to the model’s documented total-entry limit. The feature does not change the schedule: masking digits cannot make a password valid outside its active hours.

Choose a duration PIN for a defined stay

Use a duration password for a house sitter, short-term guest, or other visitor whose access should cover a continuous, bounded period. The manual describes duration passwords as automatically expiring when the stay ends.

Duration passwords also support the documented anti-peep feature. If you use that feature, keep the actual PIN intact and follow the Solar Palm instructions. Do not treat anti-peep entry as a reason to give someone a longer access window than they need.

How to create and share the right code

On the Veno Solar Palm, the manual lists these Lockin Smart App paths:

  • One-time: Devices → select the lock → Settings → Temporary Password → One-Time Password → Generate Password
  • Periodic: Devices → select the lock → Settings → Temporary Password → Periodic Password
  • Duration: Devices → select the lock → Settings → Temporary Password → Duration

After generating a code, copy and share it securely. The manual says that one-time, periodic, and duration passwords cannot be retrieved after creation; if the original periodic or duration password is forgotten, the documented recovery is to delete it and generate a new one. Treat the app’s current labels and the matching model manual as the authority if a firmware revision changes the path.

When you message the visitor, include the code type and the entry instruction. For example:

This is a one-time PIN for the Lockin Veno Solar Palm. It is for one entry only and should be used within its validity window. If it does not work, contact me rather than trying different digit combinations.

For a periodic or duration password, state the schedule or stay window as well. “Guest PIN” by itself is incomplete because it does not tell the recipient whether the code is one-time, recurring, or time-bounded.

One-time PIN entry: use the code as issued

The Veno Solar Palm manual explicitly says that one-time passwords do not support anti-peep entry. Enter the one-time PIN exactly as it was generated—without adding random digits before or after it. The first touch wakes the keypad; it is not a reason to add a digit.

If the PIN is rejected, stop before experimenting with extra numbers. Ask the host to confirm the model, code type, validity window, and whether it has already been used. Repeated password attempts can trigger the lock’s wrong-try protection; the Solar Palm manual documents a temporary one-minute password lockout after the configured attempt limit is reached. Palm-vein or other non-password authentication may remain available during that password-only lockout, but a visitor should use only an authorized alternative arranged by the owner.

For more detail on a password lockout, see what happens after too many wrong smart-lock attempts. For model documentation, use the Lockin user-manual library.

A simple rule for hosts

Match the code to the visit, then match the instructions to the code:

  • One visit: one-time PIN, exact digits, no anti-peep padding.
  • Repeating schedule: periodic PIN, scheduled active hours, documented anti-peep support.
  • Defined stay: duration PIN, expiry at the end of the stay, documented anti-peep support.

The Lockin Veno Solar Palm product page also links temporary access to guests, cleaners, and dog walkers, but the exact code behavior is model-specific. Before creating access on another Lockin smart lock, check that model’s current manual rather than copying the Veno Solar Palm rule.

The safest next step is to open the Lockin Smart App, identify the visit pattern, and create only the narrowest credential that covers it. That keeps a one-time PIN one-time and makes a recurring or time-bounded guest visit easier to manage.
